Garrison
For centuries, the lighthouse has provided guidance and safe passage
for sailors. Similarly, Garrison/Noreen/Brewer has successfully guided
millions of students through managerial accounting, helping them sail
smoothly through the course.
Decades ago, lighthouses were still being operated manually. In these
days of digital transformation, lighthouses are run using automatic lamp
changers and other modern devices. In much the same way, Garrison/
Noreen/Brewer has evolved over the years. Today, the Garrison book
not only guides students—accounting majors and other business majors
alike—safely through the course but is enhanced by a number of powerful
new tools to augment student learning and increase student motivation.
McGraw-Hill Connect Accounting and the LearnSmart Advantage Suite
offer a number of features to facilitate student learning. NEW Intelligent
Resource Technology interface for Connect Accounting includes improved
answer acceptance for formatting issues, a general journal application
that looks and feels more like a general ledger software package, and
table entry for select problems so students can complete calculations
online. Animated, narrated Interactive Presentations for each learning
objective teach the core concepts of the text and animated, narrated
Guided Examples connected to practice exercises provide a step-by-step
walkthrough of a similar exercise, assisting students when they need
it most. The student library within Connect gives students access to
additional resources, such as forms for the Applying Excel feature, an
electronic version of the textbook, and more.
The NEW LearnSmart Advantage Suite, powerful products fueled by
the proven McGraw-Hill LearnSmart engine, include additional learning
resources in LearnSmart Achieve and the first ever adaptive eBook
experience in SmartBook. These products utilize data collected from
over 2 million student users and advanced scientific algorithms to ensure
that every minute a student spends studying is the most efficient and
productive minute possible for that individual student.
Just as the lighthouse continues to provide reliable guidance to seafarers,
the Garrison/Noreen/Brewer book continues its tradition of helping students
sail successfully through managerial accounting by always focusing on three
important qualities: relevance, accuracy, and clarity.

RELEVANCE.
Every effort is made to help students
relate the concepts in this book to the decisions made by working
managers. In the fifteenth edition, the authors have added a new
section to Chapter 1 titled Managerial Accounting: Beyond the
Numbers, which has expanded coverage of leadership skills with
the goal of helping all business students better understand why
managerial accounting is relevant to their future careers. New and
revised In Business boxes throughout the book link chapter concepts
to pertinent real-world examples. Service industry references appear
throughout the chapter narrative and end-of-chapter material to
provide students with relevant context for the material they are
learning. The robust Connect Accounting technology package and
the LearnSmart Advantage Suite include new and exciting tools
to help keep students engaged in the learning process. For these
reasons and many more, a student reading Garrison should never
have to ask “Why am I learning this?”
Ann K. Brooks,
University of New Mexico
The authors have done
a great job explaining
managerial accounting
concepts and providing realworld examples that students
can relate to.

ACCURACY.
The Garrison book continues to set
the standard for accurate and reliable material in its fifteenth
edition. With each revision, the authors evaluate the book and its
supplements in their entirety, working diligently to ensure that
the end-of-chapter material, solutions manual, and test bank are
consistent, current, and accurate.
CLARITY. Generations of students have praised Garrison
for the friendliness and readability of its writing, but that’s just
the beginning. In the fifteenth edition, the authors have rewritten
various chapters with input and guidance from instructors around
the country to ensure that teaching and learning from Garrison
remains as easy as it can be.
The authors’ steady focus on these three core elements has led
to tremendous results. Managerial Accounting has consistently led
the market, being used by over two million students and earning
a reputation for reliability that other texts aspire to match.
Managerial Accounting
Garrison does a superior job
of introducing Managerial
Accounting and necessary
management skills. In
addition, the textbook
discusses the crucial
topics of why managerial
accounting matters to one’s
career, ethics, and social
responsibility.
It provides simple and clear
explanations of the concepts
with easy to follow examples.
It is ideal for undergraduate
and graduate level
accounting students.
Rong Huang,

The Garrison [text] is clearly
the best written managerial
accounting book that I have

engage and instruct students without cluttering the pages or interrupting student learning.
Garrison’s key pedagogical tools enhance and support students’ understanding of the
concepts rather than compete with the narrative for their attention.
The Foundational 15
Applying Excel
Available with McGraw-Hill’s Connect® Accounting.
LO4–2, LO4–3, LO4–4,
LO4–5
NEW to the fifteenth edition of Garrison!
Each chapter now contains one Foundational 15 exercise
that includes 15 “building-block” questions related to
one concise set of data. These exercises can be used for
in-class discussion or as homework assignments. They are
found before the Exercises and are available in Connect
Accounting.
The Excel worksheet form that appears below is to be used to recreate the extended example on
pages 153–155. Download the workbook containing this form from the Online Learning Center at
www.mhhe.com/garrison15e. On the website you will also receive instructions about how to use
this worksheet form.
Applying Excel
This end-of-chapter feature links the power of
Excel with managerial accounting concepts by
illustrating how Excel functionality can be used to better
understand accounting data. Applying Excel goes beyond
plugging numbers into a template by providing students
with an opportunity to build their own Excel worksheets
and formulas. Students are then asked “what if”
questions in which they analyze not only how related
pieces of accounting data affect each other but why
they do. Applying Excel immediately precedes the Exercises in twelve of the fifteen chapters in the book and is
also integrated with McGraw-Hill’s Connect ® Accounting, allowing students to practice their skills online with
algorithmically generated datasets.
You should proceed to the requirements below only after completing your worksheet.
Required:
1.
Check your worksheet by changing the beginning work in process inventory to 100
units, the units started into production during the period to 2,500 units, and the units in
ending work in process inventory to 200 units, keeping all of the other data the same as
in the original example. If your worksheet is operating properly, the cost per equivalent
unit for materials should now be $152.50 and the cost per equivalent unit for conversion

Melanie Anderson, Slippery Rock University
[Applying Excel is] an excellent way for students to programmatically develop spreadsheet
skills without having to be taught spreadsheet techniques by the instructor. A significant
associated benefit is that students gain more exposure to the dynamics of accounting

Process Costing
If you have ever spilled milk,
there is a good chance that
you used Bounty paper
towels to clean up the
mess. Procter & Gamble
(P&G) manufactures Bounty
in two main processing
departments—Paper Making and Paper Converting.
In the Paper Making Department, wood pulp is converted into paper and then
spooled into 2,000 pound
rolls. In the Paper Converting Department, two of the
2,000 pound rolls of paper
are simultaneously unwound
into a machine that creates
a two-ply paper towel that is
decorated, perforated, and
embossed to create texture.
The large sheets of paper
towels that emerge from
this process are wrapped
around a cylindrical cardboard core measuring eight feet in length. Once
enough sheets wrap around the core, the eight foot roll is cut into individual
rolls of Bounty that are sent down a conveyor to be wrapped, packed, and
shipped.
In this type of manufacturing environment, costs cannot be readily traced to
individual rolls of Bounty; however, given the homogeneous nature of the product, the total costs incurred in the Paper Making Department can be spread
uniformly across its output of 2,000 pound rolls of paper. Similarly, the total
costs incurred in the Paper Converting Department (including the cost of the
2,000 pound rolls that are transferred in from the Paper Making Department)
can be spread uniformly across the number of cases of Bounty produced.
P&G uses a similar costing approach for many of its products such as
Tide, Crest toothpaste, and Dawn dishwashing liquid. ■

IN BUSINESS
THE DIFFERENCE BETWEEN LABOR RATES AND LABOR COST
In Business Boxes
The emergence of China as a global competitor has increased the need for managers to understand the difference between labor rates and labor cost. Labor rates reflect the amount paid to
employees per hour or month. Labor costs measure the employee compensation paid per unit of
output. For example, Tenneco has plants in Shanghai, China, and Litchfield, Michigan, that both
manufacture exhaust systems for automobiles. The monthly labor rate per employee at the Shanghai plant ranges from $210–$250, whereas the same figure for the Litchfield plant ranges from
$1,880–$4,064. A naïve interpretation of these labor rates would be to automatically assume that
the Shanghai plant is the lower labor cost facility. A wiser comparison of the two plants’ labor costs
would account for the fact that the Litchfield plant produced 1.4 million exhaust systems in 2005
compared to 400,000 units at the Shanghai plant, while having only 20% more employees than the
Shanghai plant.
In-depth, clear
coverage; interesting

COMPUTING MARGIN OF SAFETY FOR A SMALL BUSINESS
205
IN BUSINESS
Sam Calagione owns Dogfish Head Craft Brewery, a microbrewery in Rehobeth Beach, Delaware.
He charges distributors as much as $100 per case for his premium beers such as World Wide
Stout. The high-priced microbrews bring in $800,000 in operating income on revenue of $7 million.
Calagione reports that his raw ingredients and labor costs for one case of World Wide Stout are
$30 and $16, respectively. Bottling and packaging costs are $6 per case. Gas and electric costs
are about $10 per case.
If we assume that World Wide Stout is representative of all Dogfish microbrews, then we can
compute the company’s margin of safety in five steps. First, variable cost as a percentage of sales
is 62% [($30 1 $16 1 $6 1 $10)/$100]. Second, the contribution margin ratio is 38% (1 2 0.62).
Third, Dogfish’s total fixed cost is $1,860,000 [($7,000,000 3 0.38) 2 $800,000]. Fourth, the
break-even point in dollar sales is $4,894,737 ($1,860,000/0.38). Fifth, the margin of safety is

Prem Narayan and Bob Luchinni met to discuss the results of Bob’s analysis.
Prem: Bob, everything you have shown me is pretty clear. I can see what impact the
sales manager’s suggestions would have on our profits. Some of those suggestions
are quite good and others are not so good. I am concerned that our margin of safety
is only 50 speakers. What can we do to increase this number?
Bob: Well, we have to increase total sales or decrease the break-even point or both.
Prem: And to decrease the break-even point, we have to either decrease our fixed
expenses or increase our unit contribution margin?
Bob: Exactly.
Prem: And to increase our unit contribution margin, we must either increase our selling
price or decrease the variable cost per unit?
Bob: Correct.
Prem: So what do you suggest?
Bob: Well, the analysis doesn’t tell us which of these to do, but it does indicate we have
a potential problem here.
Prem: If you don’t have any immediate suggestions, I would like to call a general meeting next week to discuss ways we can work on increasing the margin of safety. I
think everyone will be concerned about how vulnerable we are to even small downturns in sales.

lives. Students are shown
step-by-step how accounting
concepts are implemented
in organizations and how
these concepts are applied to solve everyday business problems. First,
“The Issue” is introduced through a dialogue; the student then walks
through the implementation process; finally, “The Wrap-up” summarizes
the big picture.
CVP Considerations in Choosing a Cost Structure
Cost structure refers to the relative proportion of fixed and variable costs in an organization. Managers often have some latitude in trading off between these two types of costs.
For example, fixed investments in automated equipment can reduce variable labor costs.
In this section, we discuss the choice of a cost structure. We also introduce the concept of
operating leverage.
Which cost structure is better—high variable costs and low fixed costs, or the opposite?
No single answer to this question is possible; each approach has its advantages. To show
what we mean, refer to the following contribution format income statements for two

Managerial Accounting has earned a reputation for the best
end-of-chapter practice material of any text on the market.
Our problem and case material continues to conform to
AACSB recommendations and makes a great starting point
for class discussions and group projects. When Ray Garrison
first wrote Managerial Accounting, he started with the endof-chapter material, then wrote the narrative in support of it.
This unique approach to textbook authoring not only ensured
consistency between the end-of-chapter material and text
content but also underscored Garrison’s fundamental belief
in the importance of applying theory through practice. It is not
enough for students to read, they must also understand. To
this day, the guiding principle of that first edition remains, and
Garrison’s superior end-of-chapter material continues to provide
accurate, current, and relevant practice for students.

Exercises
All applicable exercises are available with McGraw-Hill’s Connect® Accounting.
EXERCISE 3–1 Compute the Predetermined Overhead Rate [LO3–1]
Harris Fabrics computes its predetermined overhead rate annually on the basis of direct laborhours. At the beginning of the year, it estimated that 20,000 direct labor-hours would be required
for the period’s estimated level of production. The company also estimated $94,000 of fixed manufacturing overhead expenses for the coming period and variable manufacturing overhead of $2.00
per direct labor-hour. Harris’s actual manufacturing overhead for the year was $123,900 and its
actual total direct labor was 21,000 hours.
Required:
Compute the company’s predetermined overhead rate for the year.
EXERCISE 3–2 Apply Overhead [LO3–2]
Luthan Company uses a predetermined overhead rate of $23.40 per direct labor-hour. This predetermined rate was based on a cost formula that estimated $257,400 of total manufacturing overhead for an estimated activity level of 11,000 direct labor-hours.
The company incurred actual total manufacturing overhead costs of $249,000 and 10,800
total direct labor
hours during the period.

Utilizing the Icons
To reflect our service-based economy, the text is replete
with examples from service-based businesses. A helpful
icon distinguishes service-related examples in the text.
David Krug, Johnson County
Community College
Business Ethics are of
growing importance and
the coverage early in the
book is commendable.
The IFRS icon highlights content that may be affected by
the impending change to IFRS and possible convergence
between U.S. GAAP and IFRS.
Heminigild Mpundu,
University of Northern Iowa
Ethics assignments and examples serve as a reminder that
good conduct is vital in business. Icons call out content
that relates to ethical behavior for students.
The writing icon denotes problems that require students
to use critical thinking as well as writing skills to explain
their decisions.

New to the
Fifteenth Edition
Faculty feedback helps us continue to improve Managerial Accounting. In response to reviewer suggestions, the
authors have made the following changes to the text:
• All chapters have the NEW Foundational 15 end-of-chapter feature.
• New In Business boxes have been added throughout to provide relevant and updated real-world examples
for use in classroom discussion and to support student understanding of key concepts as they read through a
chapter.
• The end-of-chapter practice material has been updated throughout.
• Several chapters (Chapters 2, 8, and 13) now better highlight the dynamic nature and power of Excel as a tool for
managerial accounting.
Chapter 1
This chapter has a new section titled Managerial
Accounting: Beyond the Numbers. It has expanded
coverage of leadership skills and an expanded set of
end-of-chapter exercises.
Chapter 2
The learning objective pertaining to direct and indirect
costs has been moved to the front of the chapter
to improve the students’ ability to understand the
material. Appendix 2A has been overhauled to simplify
the explanation of how to use Microsoft Excel to
perform least-squares regression analysis.
Chapter 3
This chapter has added Appendix 3A: ActivityBased Absorption Costing; this material was formerly
Appendix 7B in the previous edition of the book.
Moving this material to Chapter 3 offers instructors
greater flexibility when determining how to cover
activity-based costing.
Chapter 4
Updated with a new In Business box.
Chapter 5
The assumptions of CVP analysis have been moved
from the end of the chapter to the beginning of the
chapter. The target profit analysis and break-even
analysis learning objectives have been reversed.
Chapter 6
This chapter has added a new learning objective related
to calculating companywide and segment break-even
points for companies with traceable fixed costs. It has
also added a new appendix related to super-variable
costing.
Chapter 7
This chapter has added a new exhibit and accompanying
text to better explain key concepts and terminology
within the chapter.
Managerial Accounting

Chapter 8
This chapter has been renamed, and we have added new
text and an exhibit to help students better understand
how and why a master budget is created and how
Microsoft Excel can be used to create a financial
planning model that answers “what-if” questions. Two
new end-of-chapter exercises that enable students to
use Microsoft Excel to answer “what-if” questions have
also been added.
Chapter 9
A discussion of the variance analysis cycle and
management by exception has been inserted in the
front of this chapter; this material was previously
included in the standard costing chapter. In response
to customer feedback, we reversed the headings in the
flexible budget performance report. The actual results
are shown in the far-left column and the planning
budget is shown in the far-right column.
Chapter 10
In response to customer feedback, we reversed the
headings in the general model for standard cost
variance analysis. The actual results (AQ 3 AP) are
shown in the far-left column and the flexible budget
(SQ 3 SP) is shown in the far-right column.
Chapter 12
A section illustrating the meaning of a constraint has
been added. Also, several new In Business boxes have
been created.
Chapter 13
The learning objective pertaining to the payback
period has been moved to the front of the chapter.
A Microsoft Excel-based approach has been adopted
for depicting net present value calculations. We have
added a discussion of the behavioral implications of
the simple rate of return method. Appendix 13C has
been completely overhauled so that students can more
easily grasp the impact of income taxes on net present
value analysis.
Chapter 14
This chapter has been updated with new In Business
boxes.
Chapter 15
This chapter’s learning objectives have all been
redefined to emphasize an internal management
perspective. Four new ratios have been added to the text
to further enrich the students’ learning opportunities.
Chapter 11
This chapter has a new Business Focus feature and
two new In Business boxes.

Learn with Adaptive
Technology
Each innovative product in the LearnSmart Advantage suite is powered by the proven McGraw-Hill LearnSmart engine that has
helped over 2 million student users answer nearly 1.5 billion questions since 2009. All this data has been harnessed to make the
LearnSmart Advantage products the most intelligent, reliable, and effective adaptive learning tools that are available to students.
With products that span the entire learning process from course preparation to providing the first adaptive reading experience,
LearnSmart Advantage is the most widely used and intelligent suite of adaptive study resources available today. This innovative
series of adaptive learning products is designed to deliver demonstrable results in boosting grades, increasing course retention,
and strengthening memory recall.
These powerful products in the LearnSmart Advantage Suite are available with Garrison 15e:
LearnSmart
An adaptive self-study technology that guarantees students are learning faster,
studying more efficiently, and retaining more knowledge. As LearnSmart gets to know
each individual student user, it identifies what a student does or does not know,
ensuring that the most valuable information is presented to maximize each minute of
time spent studying. LearnSmart also pinpoints areas that a student is most likely to
forget and encourages periodic review so that knowledge is truly learned and retained.
Students who use LearnSmart are 35% more likely to complete their class; 13% more
likely to pass their class; and have been proven to improve their performance by a
full letter grade.
How Does LearnSmart work?
A student begins by answering a series of questions related to core concepts and key themes from the selected chapter(s). For each
question answered, a student will be asked to provide a confidence rating, acknowledging their level of knowledge. LearnSmart uses
this information, in tandem with the answer itself, to improve the individual learning path by adjusting which questions to present,
as well as the difficulty of these questions. Throughout the study session, students can monitor their progress by viewing a series of
performance reports that reinforce the content they need to study. They can also compare their score to their classmates and other
students from around the world. LearnSmart revisits the content a student is struggling with to convert knowledge to long-term memory
and improve overall retention of information.
SmartBook
As the first and only adaptive reading experience, SmartBook is changing the way students
read and learn. SmartBook creates a personalized reading experience by highlighting the
most important concepts a student needs to learn at that moment in time. The reading
experience continuously adapts by highlighting content based on what each student knows
and doesn’t know. This ensures that he or she is focused on the content needed to close
specific knowledge gaps, while simultaneously promoting long-term learning. Valuable
reports provide instructors insight as to how students are progressing through textbook
content, and are useful for shaping in-class time or assessment.
Managerial Accounting
F if t e e nt h E d i t i on
xvii
How Does SmartBook Work?
Each SmartBook contains four components: Preview, Read, Practice, and Recharge. Starting with an initial preview of each
chapter and key learning objectives, students read the material and are guided to topics that need the most practice based
on their responses to a continuously adapting diagnostic. Read and practice continue until SmartBook directs students to
recharge important material they are most likely to forget to ensure concept mastery and retention.
LearnSmart Achieve
A revolutionary new learning system that combines a continually adaptive
learning experience with rich, dynamic resources for student achievement.
As a student progresses through LearnSmart Achieve, the program’s
continuously adaptive learning path adjusts to deliver just-in-time videos
catered to his or her specific needs.
FPO
How Does LearnSmart Achieve Work?
LearnSmart Achieve uses a simple three-phase process to help students
achieve academic success:
Tune In—Students are asked a sample series of questions related to a specific learning objective to assess their baseline
understanding of the content and identify knowledge gaps.
Focus—Based on their responses to the Tune In questions, Achieve presents learning resources to teach the concepts that
each student struggles with most.
Practice—After the Focus phase, Achieve asks students a more in-depth series of questions to confirm their understanding
of the key objectives and adjusts accordingly, providing suggested learning resources to assist students in mastering all core
concepts.

Assurance of Learning Ready
Many educational institutions today are focused on the notion of
assurance of learning, an important element of some accreditation
standards. Managerial Accounting, 15e, is designed specifically to
support your assurance of learning initiatives with a simple, yet
powerful, solution.
Each test bank question for Managerial Accounting, 15e,
maps to a specific chapter learning outcome/objective listed
in the text. You can use our test bank software, EZ Test, to
easily query for learning outcomes/objectives that directly relate
to the learning objectives for your course. You can then use
the reporting features of EZ Test to aggregate student results
in similar fashion, making the collection and presentation of
assurance of learning data simple and easy.
AACSB Statement
The McGraw-Hill Companies, Inc., is a proud corporate member
of AACSB International. Recognizing the importance and value of
AACSB accreditation, we have sought to recognize the curricula
guidelines detailed in AACSB standards for business accreditation
by connecting selected questions in Managerial Accounting, 15e, to
the general knowledge and skill guidelines found in the AACSB
standards. The statements contained in Managerial Accounting, 15e,
are provided only as a guide for the users of this text. The AACSB
leaves content coverage and assessment clearly within the realm
and control of individual schools, the mission of the school, and the
faculty. The AACSB does also charge schools with the obligation
of doing assessment against their own content and learning goals.
While Managerial Accounting, 15e, and its teaching package make
no claim of any specific AACSB qualification or evaluation, we
have, within Managerial Accounting, 15e, labeled selected questions
according to the six general knowledge and skills areas. The labels
or tags within Managerial Accounting, 15e, are as indicated. There
are, of course, many more within the test bank, the text, and
the teaching package which might be used as a “standard” for
your course. However, the labeled questions are suggested for your
consideration.
Online Learning Center (www.mhhe.com/

The password protected instructor side of the book’s Online
Learning Center (OLC) houses all the instructor resources you

CHAPTER 1
Managerial Accounting:
An Overview
Managerial Accounting: It’s More
Than Just Crunching Numbers
BUSIN ESS FO CUS
“Creating value through values” is the credo of today’s management accountant. It means that management accountants should maintain an unwavering commitment to ethical values while using their knowledge and skills to
influence decisions that create value for organizational stakeholders. These
skills include managing risks and implementing strategy through planning,
budgeting and forecasting, and decision support. Management accountants
are strategic business partners who understand the financial and operational
sides of the business. They not only report and analyze financial measures,
but also nonfinancial measures of process performance and corporate social
performance. Think of these responsibilities as profits (financial statements),
process (customer focus and satisfaction), people (employee learning and
satisfaction), and planet (environmental stewardship). ■

his chapter explains why managerial accounting is important to the future careers of all business students. It begins by answering two
questions: (1) What is managerial accounting? and (2) Why does managerial
accounting matter to your career? It concludes by discussing six topics—ethics,
strategic management, enterprise risk management, corporate social responsibility, process management, and leadership—that define the business context for applying the
quantitative aspects of managerial accounting.

Managerial Accounting: An Overview
financial and managerial accounting is that financial accounting serves the needs of those
outside the organization, whereas managerial accounting serves the needs of managers employed inside the organization. Because of this fundamental difference in users,
financial accounting emphasizes the financial consequences of past activities, objectivity and verifiability, precision, and companywide performance, whereas managerial
accounting emphasizes decisions affecting the future, relevance, timeliness, and segment
performance. A segment is a part or activity of an organization about which managers
would like cost, revenue, or profit data. Examples of business segments include product
lines, customer groups (segmented by age, ethnicity, gender, volume of purchases, etc.),
geographic territories, divisions, plants, and departments. Finally, financial accounting
is mandatory for external reports and it needs to comply with rules, such as generally
accepted accounting principles (GAAP) and international financial reporting standards
(IFRS), whereas managerial accounting is not mandatory and it does not need to comply
with externally imposed rules.
As mentioned in Exhibit 1–1, managerial accounting helps managers perform three
vital activities—planning, controlling, and decision making. Planning involves establishing goals and specifying how to achieve them. Controlling involves gathering feedback
to ensure that the plan is being properly executed or modified as circumstances change.
Decision making involves selecting a course of action from competing alternatives. Now
let’s take a closer look at these three pillars of managerial accounting.
Planning
Assume that you work for Procter & Gamble (P&G) and that you are in charge of
the company’s campus recruiting for all undergraduate business majors. In this example,
your planning process would begin by establishing a goal such as: our goal is to recruit
the “best and brightest” college graduates. The next stage of the planning process would
require specifying how to achieve this goal by answering numerous questions such as:
•
•
•
•
•
•
•
How many students do we need to hire in total and from each major?
What schools do we plan to include in our recruiting efforts?
Which of our employees will be involved in each school’s recruiting activities?
When will we conduct our interviews?
How will we compare students to one another to decide who will be extended job offers?
What salary will we offer our new hires? Will the salaries differ by major?
How much money can we spend on our recruiting efforts?
As you can see, there are many questions that need to be answered as part of the planning process. Plans are often accompanied by a budget. A budget is a detailed plan for
the future that is usually expressed in formal quantitative terms. As the head of recruiting
at P&G, your budget would include two key components. First, you would have to work
with other senior managers inside the company to establish a budgeted amount of total
salaries that can be offered to all new hires. Second, you would have to create a budget
that quantifies how much you intend to spend on your campus recruiting activities.
Controlling
Once you established and started implementing P&G’s recruiting plan, you would transition to the control process. This process would involve gathering, evaluating, and
responding to feedback to ensure that this year’s recruiting process meets expectations.
It would also include evaluating the feedback in search of ways to run a more effective
recruiting campaign next year. The control process would involve answering questions
such as:
•
•
Did we succeed in hiring the planned number of students within each major and at
each school?
Did we lose too many exceptional candidates to competitors?

Chapter 1
•
•
•
•
•
Did each of our employees involved in the recruiting process perform satisfactorily?
Is our method of comparing students to one another working?
Did the on-campus and office interviews run smoothly?
Did we stay within our budget in terms of total salary commitments to new hires?
Did we stay within our budget regarding spending on recruiting activities?
As you can see, there are many questions that need to be answered as part of the control process. When answering these questions your goal would be to go beyond simple
yes or no answers in search of the underlying reasons why performance exceeded or
failed to meet expectations. Part of the control process includes preparing performance
reports. A performance report compares budgeted data to actual data in an effort to
identify and learn from excellent performance and to identify and eliminate sources of
unsatisfactory performance. Performance reports can also be used as one of many inputs
to help evaluate and reward employees.
Although this example focused on P&G’s campus recruiting efforts, we could have
described how planning enables FedEx to deliver packages across the globe overnight,
or how it helped Apple develop and market the iPad. We could have discussed how the
control process helps Pfizer, Eli Lilly, and Abbott Laboratories ensure that their pharmaceutical drugs are produced in conformance with rigorous quality standards, or how
Kroger relies on the control process to keep its grocery shelves stocked. We also could
have looked at planning and control failures such as BP’s massive oil spill in the Gulf of
Mexico. In short, all managers (and that probably includes you someday) perform planning and controlling activities.
Decision Making
Perhaps the most basic managerial skill is the ability to make intelligent, data-driven
decisions. Broadly speaking, many of those decisions revolve around the following
three questions. What should we be selling? Who should we be serving? How should we
execute? Exhibit 1–2 provides examples of decisions pertaining to each of these three
categories.
The left-hand column of Exhibit 1–2 suggests that every company must make
decisions related to the products and services that it sells. For example, each year
Procter & Gamble must decide how to allocate its marketing budget across 25 brands
that each generates over $1 billion in sales as well as other brands that have promising growth potential. Mattel must decide what new toys to introduce to the market. Southwest Airlines must decide what ticket prices to establish for each of its

Managerial Accounting: An Overview
thousands of flights per day. General Motors must decide whether to discontinue
certain models of automobiles.
The middle column of Exhibit 1–2 indicates that all companies must make decisions related to the customers that they serve. For example, Sears must decide how to
allocate its marketing budget between products that tend to appeal to male versus female
customers. FedEx must decide whether to expand its services into new markets across
the globe. Hewlett-Packard must decide what price discounts to offer corporate clients
that purchase large volumes of its products. A bank must decide whether to discontinue
customers that may be unprofitable.
The right-hand column of Exhibit 1–2 shows that companies also make decisions
related to how they execute. For example, Boeing must decide whether to rely on outside
vendors such as Goodrich, Saab, and Rolls-Royce to manufacture many of the parts
used to make its airplanes. Cintas must decide whether to expand its laundering and
cleaning capacity in a given geographic region by adding square footage to an existing
facility or by constructing an entirely new facility. In an economic downturn, a manufacturer might have to decide whether to eliminate one 8-hour shift at three plants or to close
one plant. Finally, all companies have to decide among competing improvement opportunities. For example, a company may have to decide whether to implement a new software
system, to upgrade a piece of equipment, or to provide extra training to its employees.
This portion of the chapter has explained that the three pillars of managerial accounting are planning, controlling, and decision making. This book helps prepare you to
become an effective manager by explaining how to make intelligent data-driven decisions, how to create financial plans for the future, and how to continually make progress
toward achieving goals by obtaining, evaluating, and responding to feedback.
Why Does Managerial Accounting Matter to Your Career?
Many students feel anxious about choosing a major because they are unsure if it will
provide a fulfilling career. To reduce these anxieties, we recommend deemphasizing what
you cannot control about the future; instead focusing on what you can control right now.
More specifically, concentrate on answering the following question: What can you do
now to prepare for success in an unknown future career? The best answer is to learn
skills that will make it easier for you to adapt to an uncertain future. You need to become
adaptable!
Whether you end up working in the United States or abroad, for a large corporation, a
small entrepreneurial company, a nonprofit organization, or a governmental entity, you’ll
need to know how to plan for the future, how to make progress toward achieving goals,
and how to make intelligent decisions. In other words, managerial accounting skills are
useful in just about any career, organization, and industry. If you commit energy to this
course, you’ll be making a smart investment in your future—even though you cannot
clearly envision it. Next, we will elaborate on this point by explaining how managerial
accounting relates to the future careers of business majors and accounting majors.
Business Majors
Exhibit 1–3 provides examples of how planning, controlling, and decision making affect
three majors other than accounting—marketing, supply chain management, and human
resource management.
The left-hand column of Exhibit 1–3 describes some planning, controlling, and
decision-making applications in the marketing profession. For example, marketing managers make planning decisions related to allocating advertising dollars across various
communication mediums and to staffing new sales territories. From a control standpoint, they may closely track sales data to see if a budgeted price cut is generating an

anticipated increase in unit sales, or they may study inventory levels during the holiday
shopping season so that they can adjust prices as needed to optimize sales. Marketing managers also make many important decisions such as whether to bundle services
together and sell them for one price or to sell each service separately. They may also
decide whether to sell products directly to the customer or to sell to a distributor, who
then sells to the end consumer.
The middle column of Exhibit 1–3 states that supply chain managers have to plan
how many units to produce to satisfy anticipated customer demand. They also need to
budget for operating expenses such as utilities, supplies, and labor costs. In terms of
control, they monitor actual spending relative to the budget, and closely watch operational measures such as the number of defects produced relative to the plan. Supply chain
managers make numerous decisions, such as deciding whether to transfer production of a
component part to an overseas supplier. They also decide whether to invest in redesigning
a manufacturing process to reduce inventory levels.
The right-hand column of Exhibit 1–3 explains how human resource managers
make a variety of planning decisions, such as budgeting how much to spend on occupational safety training and employee recruitment advertising. They monitor feedback
related to numerous management concerns, such as employee retention rates and the
timely completion of employee performance appraisals. They also help make many
important decisions such as whether to hire on-site medical staff in an effort to lower
health care costs, and whether to hire temporary workers or full-time employees in an
uncertain economy.
Managerial Accounting: An Overview
7
For brevity, Exhibit 1–3 does not include all business majors, such as finance, management information systems, and economics. Can you explain how planning, controlling, and decision-making activities would relate to these majors?
Accounting Majors
Many accounting graduates begin their careers working for public accounting firms that
provide a variety of valuable services for their clients. Some of these graduates will build
successful and fulfilling careers in the public accounting industry; however, most will leave
public accounting at some point to work in other organizations. In fact, the Institute of
Management Accountants (IMA) estimates that more than 80% of professional accountants in the United States work in nonpublic accounting environments (www.imanet.org/
about_ima/our_mission.aspx).
The public accounting profession has a strong financial accounting orientation. Its
most important function is to protect investors and other external parties by assuring
them that companies are reporting historical financial results that comply with applicable
accounting rules. Managerial accountants also have strong financial accounting skills.
For example, they play an important role in helping their organizations design and maintain financial reporting systems that generate reliable financial disclosures. However, the
primary role of managerial accountants is to partner with their co-workers within the
organization to improve performance.
Given the 80% figure mentioned above, if you are an accounting major there is a
very high likelihood that your future will involve working for a nonpublic accounting
employer. Your employer will expect you to have strong financial accounting skills, but
more importantly, it will expect you to help improve organizational performance by
applying the planning, controlling, and decision-making skills that are the foundation of
managerial accounting.
A NETWORKING OPPORTUNITY
The Institute of Management Accountants (IMA) is a network of more than 60,000 accounting and
finance professionals from over 120 countries. Every year the IMA hosts a student leadership
conference that attracts 300 students from over 50 colleges and universities. Guest speakers at
past conferences have discussed topics such as leadership, advice for a successful career, how
to market yourself in a difficult economy, and excelling in today’s multigenerational workforce. One
student who attended the conference said, “I liked that I was able to interact with professionals who
are in fields that could be potential career paths for me.” For more information on this worthwhile
networking opportunity, contact the IMA at the phone number and website shown below.

Professional Certification—A Smart Investment If you plan to become
an accounting major, the Certified Management Accountant (CMA) designation is a
globally respected credential (sponsored by the IMA) that will increase your credibility,
upward mobility, and compensation. Exhibit 1–4 summarizes the topics covered in the
two-part CMA exam. For brevity, we are not going to define all the terms included in
this exhibit. Its purpose is simply to emphasize that the CMA exam focuses on the planning, controlling, and decision-making skills that are critically important to nonpublic
accounting employers. The CMA’s internal management orientation is a complement to
the highly respected Certified Public Accountant (CPA) exam that focuses on rule-based
compliance—assurance standards, financial accounting standards, business law, and the
tax code. Information about becoming a CMA is available on the IMA’s website (www.
imanet.org) or by calling 1-800-638-4427.

Managerial Accounting: Beyond the Numbers
Exhibit 1–5 summarizes how each chapter of the book teaches measurement skills that
managers use on the job every day. For example, Chapter 8 teaches you the measurement
skills that managers use to answer the question—how should I create a financial plan
for next year? Chapters 9 and 10 teach you the measurement skills that managers use to
answer the question—how well am I performing relative to my plan? Chapter 7 teaches
you measurement skills related to product, service, and customer profitability. However,
it is vitally important that you also understand managerial accounting involves more than
just “crunching numbers.” To be successful, managers must complement their measurement skills with six business management perspectives that “go beyond the numbers” to
enable intelligent planning, control, and decision making.

An Ethics Perspective
Ethical behavior is the lubricant that keeps the economy running. Without that lubricant,
the economy would operate much less efficiently—less would be available to consumers,
quality would be lower, and prices would be higher. In other words, without fundamental
trust in the integrity of business, the economy would operate much less efficiently. Thus,
for the good of everyone—including profit-making companies—it is vitally important
that business be conducted within an ethical framework that builds and sustains trust.
Code of Conduct for Management Accountants The Institute of
Management Accountants (IMA) of the United States has adopted an ethical code
called the Statement of Ethical Professional Practice that describes in some detail the
ethical responsibilities of management accountants. Even though the standards were
developed specifically for management accountants, they have much broader application.
The standards consist of two parts that are presented in full in Exhibit 1–6 (page 10).
The first part provides general guidelines for ethical behavior. In a nutshell, a management accountant has ethical responsibilities in four broad areas: first, to maintain a high
level of professional competence; second, to treat sensitive matters with confidentiality;
third, to maintain personal integrity; and fourth, to disclose information in a credible
fashion. The second part of the standards specifies what should be done if an individual
finds evidence of ethical misconduct.
The ethical standards provide sound, practical advice for management accountants and managers. Most of the rules in the ethical standards are motivated by a very
practical consideration—if these rules were not generally followed in business, then

EXHIBIT 1–6
IMA Statement of Ethical Professional Practice
Members of IMA shall behave ethically. A commitment to ethical professional practice includes: overarching principles that express our values, and standards that guide our conduct.
PRINCIPLES
IMA’s overarching ethical principles include: Honesty, Fairness, Objectivity, and Responsibility. Members shall act in
accordance with these principles and shall encourage others within their organizations to adhere to them.
STANDARDS
A member’s failure to comply with the following standards may result in disciplinary action.
I. COMPETENCE
Each member has a responsibility to:
1. Maintain an appropriate level of professional expertise by continually developing knowledge and skills.
2. Perform professional duties in accordance with relevant laws, regulations, and technical standards.
3. Provide decision support information and recommendations that are accurate, clear, concise, and timely.
4. Recognize and communicate professional limitations or other constraints that would preclude responsible judgment or successful performance of an activity.
II. CONFIDENTIALITY
Each member has a responsibility to:
1. Keep information confidential except when disclosure is authorized or legally required.
2. Inform all relevant parties regarding appropriate use of confidential information. Monitor subordinates’ activities
to ensure compliance.
3. Refrain from using confidential information for unethical or illegal advantage.
III. INTEGRITY
Each member has a responsibility to:
1. Mitigate actual conflicts of interest. Regularly communicate with business associates to avoid apparent conflicts of interest. Advise all parties of any potential conflicts.
2. Refrain from engaging in any conduct that would prejudice carrying out duties ethically.
3. Abstain from engaging in or supporting any activity that might discredit the profession.
IV. CREDIBILITY
Each member has a responsibility to:
1. Communicate information fairly and objectively.
2. Disclose all relevant information that could reasonably be expected to influence an intended user’s understanding of the reports, analyses, or recommendations.
3. Disclose delays or deficiencies in information, timeliness, processing, or internal controls in conformance with
organization policy and/or applicable law.
RESOLUTION OF ETHICAL CONFLICT
In applying the Standards of Ethical Professional Practice, you may encounter problems identifying unethical
behavior or resolving an ethical conflict. When faced with ethical issues, you should follow your organization’s
established policies on the resolution of such conflict. If these policies do not resolve the ethical conflict, you should
consider the following courses of action:
1. Discuss the issue with your immediate supervisor except when it appears that the supervisor is involved. In
that case, present the issue to the next level. If you cannot achieve a satisfactory resolution, submit the issue to
the next management level. If your immediate superior is the chief executive officer or equivalent, the acceptable reviewing authority may be a group such as the audit committee, executive committee, board of directors,
board of trustees, or owners. Contact with levels above the immediate superior should be initiated only with
your superior’s knowledge, assuming he or she is not involved. Communication of such problems to authorities
or individuals not employed or engaged by the organization is not considered appropriate, unless you believe
there is a clear violation of the law.
2. Clarify relevant ethical issues by initiating a confidential discussion with an IMA Ethics Counselor or other
impartial advisor to obtain a better understanding of possible courses of action.
3. Consult your own attorney as to legal obligations and rights concerning the ethical conflict.
Managerial Accounting: An Overview
TOYOTA ENCOUNTERS MAJOR PROBLEMS
When Toyota Motor Corporation failed to meet its profit targets, the company set an aggressive
goal of reducing the cost of its auto parts by 30%. The quality and safety of the company’s automobiles eventually suffered mightily resulting in recalls, litigation, incentive campaigns, and marketing
efforts that analysts estimate will cost the company more than $5 billion. The car maker’s president, Akio Toyoda, blamed his company’s massive quality lapses on an excessive focus on profits
and market share. Similarly, Jim Press, Toyota’s former top U.S. executive, said the problems were
caused by “financially-oriented pirates who didn’t have the character to maintain a customer-first
focus.”
Sources: Yoshio Takahashi, “Toyota Accelerates Its Cost-Cutting Efforts,” The Wall Street Journal, December
23, 2009, p. B4; Mariko Sanchanta and Yoshio Takahashi, “Toyota’s Recall May Top $5 Billion,” The Wall Street
Journal, March 10, 2010, p. B2; and Norihiko Shirouzu, “Toyoda Rues Excessive Profit Focus,” The Wall Street
Journal, March 2, 2010, p. B3.
the economy and all of us would suffer. Consider the following specific examples of
the consequences of not abiding by the standards:
•
•
•
Suppose employees could not be trusted with confidential information. Then top
managers would be reluctant to distribute such information within the company
and, as a result, decisions would be based on incomplete information and operations
would deteriorate.
Suppose employees accepted bribes from suppliers. Then contracts would tend to
go to the suppliers who pay the highest bribes rather than to the most competent
suppliers. Would you like to fly in aircraft whose wings were made by the subcontractor who paid the highest bribe? Would you fly as often? What would happen to
the airline industry if its safety record deteriorated due to shoddy workmanship on
contracted parts and subassemblies?
Suppose the presidents of companies routinely lied in their annual reports and financial statements. If investors could not rely on the basic integrity of a company’s
financial statements, they would have little basis for making informed decisions.
Suspecting the worst, rational investors would pay less for securities issued by companies and may not be willing to invest at all. As a consequence, companies would
have less money for productive investments—leading to slower economic growth,
fewer goods and services, and higher prices.
Not only is ethical behavior the lubricant for our economy, it is the foundation of
managerial accounting. The numbers that managers rely on for planning, control, and
decision making are meaningless unless they have been competently, objectively, and
honestly gathered, analyzed, and reported. As your career unfolds, you will inevitably
face decisions with ethical implications. Before making such decisions, consider performing the following steps. First, define your alternative courses of action. Second,
identify all of the parties that will be affected by your decision. Third, define how each
course of action will favorably or unfavorably impact each affected party. Once you have
a complete understanding of the decision context, seek guidance from external sources
such as the IMA Statement of Ethical Professional Practice, the IMA Ethics Helpline at
(800) 245-1383, or a trusted confidant. Before executing your decision ask yourself one
final question—would I be comfortable disclosing my chosen course of action on the
front page of The Wall Street Journal?
A Strategic Management Perspective
Companies do not succeed by sheer luck; instead, they need to develop a strategy that
defines how they intend to succeed in the marketplace. A strategy is a “game plan” that
enables a company to attract customers by distinguishing itself from competitors. The focal
11
IN BUSINESS
12
Chapter 1
point of a company’s strategy should be its target customers. A company can only succeed
if it creates a reason for its target customers to choose it over a competitor. These reasons,
or what are more formally called customer value propositions, are the essence of strategy.
Customer value propositions tend to fall into three broad categories—customer
intimacy, operational excellence, and product leadership. Companies that adopt a customer intimacy strategy are in essence saying to their customers, “You should choose us
because we can customize our products and services to meet your individual needs better than our competitors.” Ritz-Carlton, Nordstrom, and Virtuoso (a premium service
travel agency) rely primarily on a customer intimacy value proposition for their success.
Companies that pursue the second customer value proposition, called operational excellence, are saying to their target customers, “You should choose us because we deliver
products and services faster, more conveniently, and at a lower price than our competitors.” Southwest Airlines, Walmart, and Google are examples of companies that succeed
first and foremost because of their operational excellence. Companies pursuing the third
customer value proposition, called product leadership, are saying to their target customers, “You should choose us because we offer higher quality products than our competitors.” Apple, Cisco Systems, and W.L. Gore (the creator of GORE-TEX® fabrics) are
examples of companies that succeed because of their product leadership.1
The plans managers set forth, the variables they seek to control, and the decisions
they make are all influenced by their company’s strategy. For example, Walmart would
not make plans to build ultra-expensive clothing boutiques because these plans would
conflict with the company’s strategy of operational excellence and “everyday low prices.”
Apple would not seek to control its operations by selecting performance measures that
focus solely on cost-cutting because those measures would conflict with its product
leadership customer value proposition. Finally, it is unlikely that Rolex would decide to
implement drastic price reductions for its watches even if a financial analysis indicated
that establishing a lower price might boost short-run profits. Rolex would oppose this
course of action because it would diminish the luxury brand that forms the foundation of
the company’s product leadership customer value proposition.

A FOUR-YEAR WAITING LIST AT VANILLA BICYCLES
Sacha White started Vanilla Bicycles in Portland, Oregon, in 2001. After eight years in business,
he had a four-year backlog of customer orders. He limits his annual production to 40–50 bikes per
year that sell for an average of $7,000 each. He uses a silver alloy that costs 20 times as much
as brass (which is the industry standard) to join titanium tubes together to form a bike frame. White
spends three hours taking a buyer’s measurements to determine the exact dimensions of the bike
frame. He has resisted expanding production because it would undermine his strategy based on
product leadership and customer intimacy. As White said, “If I ended up sacrificing what made
Vanilla special just to make more bikes, that wouldn’t be worth it to me.”

An Enterprise Risk Management Perspective
Every strategy, plan, and decision involves risks. Enterprise risk management is a process used by a company to identify those risks and develop responses to them that enable
it to be reasonably assured of meeting its goals. The left-hand column of Exhibit 1–7
provides 12 examples of the types of business risks that companies face. They range from
risks that relate to the weather to risks associated with computer hackers, complying

Implement a rigorous budget review
process
Create a report that tracks key metrics
related to compliance with the laws
with the law, employee theft, and products harming customers. The right-hand column of
Exhibit 1–7 provides an example of a control that could be implemented to help reduce
each of the risks mentioned in the left-hand column of the exhibit.2 Although these
types of controls cannot completely eliminate risks, they enable companies to proactively manage their risks rather than passively reacting to unfortunate events that have
already occurred.
In managerial accounting, companies use controls to reduce the risk that their plans
will not be achieved. For example, if a company plans to build a new manufacturing
facility within a predefined budget and time frame, it will establish and monitor control
measures to ensure that the project is concluded on time and within the budget. Risk
management is also a critically important aspect of decision making. For example, when
a company quantifies the labor cost savings that it can realize by sending jobs overseas, it
should complement its financial analysis with a prudent assessment of the accompanying

Besides using controls to reduce risks, companies can also chose other risk responses, such as accepting or avoiding a risk.

MANAGING THE RISK OF A POWER OUTAGE
Between January and April of 2010, the United States had 35 major power outages. For business
owners, these power outages can be costly. For example, a New York night club called the Smoke
Jazz and Supper Club lost an estimated $1,500 in revenue when a power outage shut down its on-line
reservation system for one night. George Pauli, the owner of Great Embroidery LLC in Mesa, Arizona,
estimates that his company has an average of six power outages every year. Since Pauli’s sewing
machines cannot resume exactly where they leave off when abruptly shut down, each power outage
costs him $120 in lost inventory. Pauli decided to buy $700 worth of batteries to keep his sewing
machines running during power outages. The batteries paid for themselves in less than one year.

risks. Will the overseas manufacturer use child labor? Will the product’s quality decline,
thereby leading to more warranty repairs, customer complaints, and lawsuits? Will the
elapsed time from customer order to delivery dramatically increase? Will terminating
domestic employees diminish morale within the company and harm perceptions within
the community? These are the types of risks that managers should incorporate into their
decision-making processes.
A Corporate Social Responsibility Perspective
Companies are responsible for creating strategies that produce financial results that satisfy stockholders. However, they also have a corporate social responsibility to serve other
stakeholders—such as customers, employees, suppliers, communities, and environmental
and human rights advocates—whose interests are tied to the company’s performance.
Corporate social responsibility (CSR) is a concept whereby organizations consider the
needs of all stakeholders when making decisions. CSR extends beyond legal compliance
to include voluntary actions that satisfy stakeholder expectations. Numerous companies, such as Procter & Gamble, 3M, Eli Lilly and Company, Starbucks, Microsoft,
Genentech, Johnson & Johnson, Baxter International, Abbott Laboratories, KPMG,
PNC Bank, Deloitte, Southwest Airlines, and Caterpillar, prominently describe their
corporate social performance on their websites.
Exhibit 1–8 presents examples of corporate social responsibilities that are of interest
to six stakeholder groups.3 If a company fails to meet the needs of these six stakeholder
groups it can adversely affect its financial performance. For example, if a company pollutes the environment or fails to provide safe and humane working conditions for its
employees, the negative publicity from environmental and human rights activists could
cause the company’s customers to defect and its “best and brightest” job candidates to
apply elsewhere—both of which are likely to eventually harm financial performance.
This explains why in managerial accounting a manager must establish plans, implement
controls, and make decisions that consider impacts on all stakeholders.
A Process Management Perspective
Most companies organize themselves by functional departments, such as the Marketing
Department, the Research and Development Department, and the Accounting Department. These departments tend to have a clearly defined “chain of command” that specifies superior and subordinate relationships. However, effective managers understand that
business processes, more so than functional departments, serve the needs of a company’s

Stakeholder-Friendly Firm,” Business Horizons, March/April 2004, pp. 27–32.

GREENPEACE LEVERAGES THE POWER OF SOCIAL MEDIA
When Nestlé purchased palm oil from an Indonesian supplier to manufacture Kit-Kat candy bars
Greenpeace International used social media to express its disapproval. Greenpeace claimed that
the Indonesian company destroyed rainforest to create its palm oil plantation; therefore, Nestlé’s
actions were contributing to global warming and endangering orangutans. Greenpeace posted
YouTube videos, added comments to Nestlé’s Facebook page, and sent Twitter Tweets to communicate its message to supporters. At one point, the number of fans on Nestlé’s Facebook page
grew to 95,000, most of them being protesters. Nestlé terminated its relationship with the supplier, which provided 1.25% of Nestlé’s palm oil needs. A Nestlé spokesperson says the difficulty
in responding to social media is to “show that we are listening, which we obviously are, while not
getting involved in a shouting match.”

most important stakeholders—its customers. A business process is a series of steps that
are followed in order to carry out some task in a business. These steps often span departmental boundaries, thereby requiring managers to cooperate across functional departments. The term value chain is often used to describe how an organization’s functional
departments interact with one another to form business processes. A value chain, as
shown in Exhibit 1–9, consists of the major business functions that add value to a company’s products and services.

Service
Managers need to understand the value chain to be effective in terms of planning,
control, and decision making. For example, if a company’s engineers plan to design a
new product, they must communicate with the Manufacturing Department to ensure that
the product can actually be produced, the Marketing Department to ensure that customers will buy the product, the Distribution Department to ensure that large volumes of
the product can be cost-effectively transported to customers, and the Accounting Department to ensure that the product will increase profits. From a control and decision-making
standpoint, managers also need to focus on process excellence instead of functional performance. For example, if the Purchasing Department focuses solely on minimizing the
cost of purchased materials, this narrowly focused attempt at cost reduction may lead to
greater scrap and rework in the Manufacturing Department, more complaints in the Customer Service Department, and greater challenges in the Marketing Department because
dissatisfied customers are turning their attention to competitors.
Managers frequently use a process management method known as lean thinking, or
what is called Lean Production in the manufacturing sector. Lean Production is a management approach that organizes resources such as people and machines around the flow
of business processes and that only produces units in response to customer orders. It is
often called just-in-time production (or JIT) because products are only manufactured in
response to customer orders and they are completed just-in-time to be shipped to customers. Lean thinking differs from traditional manufacturing methods, which organize work
departmentally and encourage departments to maximize their output even if it exceeds
customer demand and bloats inventories. Because lean thinking only allows production
in response to customer orders, the number of units produced tends to equal the number
of units sold, thereby resulting in minimal inventory. The lean approach also results in
fewer defects, less wasted effort, and quicker customer response times than traditional
production methods.
IN BUSINESS
LOUIS VUITTON IMPLEMENTS LEAN PRODUCTION
Louis Vuitton, headquartered in Paris, France, used lean production to increase its manufacturing capacity without having to build a new factory. It created U-shaped work arrangements for
teams of 10 workers, thereby freeing up 10% more floor space in its factories. The company
was able to hire 300 more workers without adding any square footage. Louis Vuitton also uses
robots and computer programs to reduce wasted leather and the time needed to perform certain tasks.

A Leadership Perspective
An organization’s employees bring diverse needs, beliefs, and goals to the workplace.
Therefore, an important role for organizational leaders is to unite the behaviors of their
fellow employees around two common themes—pursuing strategic goals and making
Managerial Accounting: An Overview
optimal decisions. To fulfill this responsibility, leaders need to understand how intrinsic
motivation, extrinsic incentives, and cognitive bias influence human behavior.
Intrinsic Motivation Intrinsic motivation refers to motivation that comes from
within us. Stop for a moment and identify the greatest accomplishment of your life. Then
ask yourself what motivated you to achieve this goal? In all likelihood, you achieved it
because you wanted to, not because someone forced you to do it. In other words, you
were intrinsically motivated. Similarly, an organization is more likely to prosper when its
employees are intrinsically motivated to pursue its interests. A leader, who employees perceive as credible and respectful of their value to the organization, can increase the extent to
which those employees are intrinsically motivated to pursue strategic goals. As your career
evolves, to be perceived as a credible leader you’ll need to possess three attributes—
technical competence (that spans the value chain), personal integrity (in terms of work
ethic and honesty), and strong communication skills (including oral presentation skills and
writing skills). To be perceived as a leader who is respectful of your co-workers’ value to
the organization, you’ll need to possess three more attributes—strong mentoring skills (to
help others realize their potential), strong listening skills (to learn from your co-workers
and be responsive to their needs), and personal humility (in terms of deferring recognition
to all employees who contribute to the organization’s success). If you possess these six
traits, then you’ll have the potential to become a leader who inspires others to readily and
energetically channel their efforts toward achieving organizational goals.
Extrinsic Incentives Many organizations use extrinsic incentives to highlight
important goals and to motivate employees to achieve them. For example, assume a company establishes the goal of reducing the time needed to perform a task by 20%. In addition, assume the company agrees to pay bonus compensation to its employees if they
achieve the goal within three months. In this example, the company is using a type of
extrinsic incentive known as a bonus to highlight a particular goal and to presumably
motivate employees to achieve it.
While proponents of extrinsic incentives rightly assert that these types of rewards can
have a powerful influence on employee behavior, many critics warn that they can also produce dysfunctional consequences. For example, suppose the employees mentioned above
earned their bonuses by achieving the 20% time reduction goal within three months.
However, let’s also assume that during those three months the quality of the employees’
output plummeted, thereby causing a spike in the company’s repair costs, product returns,
and customer defections. In this instance, did the extrinsic incentive work properly? The
answer is yes and no. The bonus system did motivate employees to attain the time reduction goal; however, it also had the unintended consequences of causing employees to
neglect product quality, thereby increasing repair costs, product returns, and customer
defections. In other words, what may have seemed like a well-intended extrinsic incentive actually produced dysfunctional results for the company. This example highlights an
important leadership challenge that you are likely to face someday—designing financial
compensation systems that fairly reward employees for their efforts without inadvertently
creating extrinsic incentives that motivate them to take actions that harm the company.
Cognitive Bias Leaders need to be aware that all people (including themselves)
possess cognitive biases, or distorted thought processes, that can adversely affect planning, controlling, and decision making. To illustrate how cognitive bias works, let’s consider the scenario of a television “infomercial” where someone is selling a product with
a proclaimed value of $200 for $19.99 if viewers call within the next 30 minutes. Why
do you think the seller claims that the product has a $200 value? The seller is relying on
a cognitive bias called anchoring bias in an effort to convince viewers that a $180 discount is simply too good to pass up. The “anchor” is the false assertion that the product
is actually worth $200. If viewers erroneously attach credibility to this contrived piece of
information, their distorted analysis of the situation may cause them to spend $19.99 on
an item whose true economic value is much less than that amount.
17
18
Chapter 1
While cognitive biases cannot be eliminated, effective leaders should take two steps
to reduce their negative impacts. First, they should acknowledge their own susceptibility to cognitive bias. For example, a leader’s judgment might be clouded by optimism
bias (being overly optimistic in assessing the likelihood of future outcomes) or selfenhancement bias (overestimating ones strengths and underestimating ones weaknesses
relative to others). Second, they should acknowledge the presence of cognitive bias in
others and introduce techniques to minimize their adverse consequences. For example,
to reduce the risks of confirmation bias (a bias where people pay greater attention to
information that confirms their preconceived notions, while devaluing information that
contradicts them) or groupthink bias (a bias where some group members support a course
of action solely because other group members do), a leader may routinely appoint independent teams of employees to assess the credibility of recommendations set forth by
other individuals and groups.
Summary
This chapter defined managerial accounting and explained why it is relevant to business and
accounting majors. It also discussed six topics—ethics, strategic management, enterprise risk
management, corporate social responsibility, process management, and leadership—that define
the context for applying the quantitative aspects of managerial accounting. The most important
goal of this chapter was to help you understand that managerial accounting matters to your future
career regardless of your major. Accounting is the language of business and you’ll need to speak it
to communicate effectively with and influence fellow managers.

Exercises
For this chapter, LearnSmart and Interactive Presentations are available with
McGraw-Hill’s Connect® Accounting.
EXERCISE 1–1 Planning and Control
Many companies use budgets for three purposes. First, they use them to plan how to deploy resources to
best serve customers. Second, they use them to establish challenging goals, or stretch targets, to motivate
employees to strive for exceptional results. Third, they use them to evaluate and reward employees.
Assume that you are a sales manager working with your boss to create a sales budget for next
year. Once the sales budget is established, it will influence how other departments within the company plan to deploy their resources. For example, the manufacturing manager will plan to produce
enough units to meet budgeted unit sales. The sales budget will also be instrumental in determining
your pay raise, potential for promotion, and bonus. If actual sales exceed the sales budget, it bodes
well for your career. If actual sales are less than budgeted sales, it will diminish your financial
compensation and potential for promotion.

Assume the company uses its sales budget for only one purpose—planning to deploy resources
in a manner that best serves customers. What thoughts would influence your estimate of future
sales as well as your boss’s estimate of future sales?
Assume the company uses its sales budget for only one purpose—motivating employees to
strive for exceptional results. What thoughts would influence your estimate of future sales as

EXERCISE 1–2 Controlling
Assume that you work for an airline unloading luggage from airplanes. Your boss has said that,
on average, each airplane contains 100 pieces of luggage. Furthermore, your boss has stated that
you should be able to unload 100 pieces of luggage from an airplane in 10 minutes. Today an airplane arrived with 150 pieces of luggage and you unloaded all of it in 13 minutes. After finishing
with the 150 pieces of luggage, your boss yelled at you for exceeding the 10 minute allowance for
unloading luggage from an airplane.
Required:
How would you feel about being yelled at for taking 13 minutes to unload 150 pieces of luggage?
How does this scenario relate to the larger issue of how companies design control systems?
EXERCISE 1–3 Decision Making
Exhibit 1–2 (see page 4) includes 12 questions related to 12 types of decisions that companies
often face. In the chapter, these 12 decisions were discussed within the context of for-profit companies; however, they are also readily applicable to nonprofit organizations. To illustrate this point,
assume that you are a senior leader, such as a president, provost, or dean, in a university setting.
Required:
For each of the 12 decisions in Exhibit 1–2, provide an example of how that type of decision might
be applicable to a university setting.
EXERCISE 1–4 Ethics and the Manager
Richmond, Inc., operates a chain of 44 department stores. Two years ago, the board of directors of
Richmond approved a large-scale remodeling of its stores to attract a more upscale clientele.
Before finalizing these plans, two stores were remodeled as a test. Linda Perlman, assistant
controller, was asked to oversee the financial reporting for these test stores, and she and other
management personnel were offered bonuses based on the sales growth and profitability of these
stores. While completing the financial reports, Perlman discovered a sizable inventory of outdated
goods that should have been discounted for sale or returned to the manufacturer. She discussed the
situation with her management colleagues; the consensus was to ignore reporting this inventory as
obsolete because reporting it would diminish the financial results and their bonuses.
Required:
1.

According to the IMA’s Statement of Ethical Professional Practice, would it be ethical for
Perlman not to report the inventory as obsolete?
Would it be easy for Perlman to take the ethical action in this situation?

EXERCISE 1–7 Ethics in Business
Consumers and attorney generals in more than 40 states accused a prominent nationwide chain of
auto repair shops of misleading customers and selling them unnecessary parts and services, from
brake jobs to front-end alignments. Lynn Sharpe Paine reported the situation as follows in “Managing for Organizational Integrity,” Harvard Business Review, Volume 72 Issue 3:
In the face of declining revenues, shrinking market share, and an increasingly competitive
market . . . management attempted to spur performance of its auto centers. . . . The automotive service advisers were given product-specific sales quotas—sell so many springs, shock
absorbers, alignments, or brake jobs per shift—and paid a commission based on sales. . . .
[F]ailure to meet quotas could lead to a transfer or a reduction in work hours. Some employees spoke of the “pressure, pressure, pressure” to bring in sales.
This pressure-cooker atmosphere created conditions under which employees felt that the
only way to satisfy top management was by selling products and services to customers that
they didn’t really need.
Suppose all automotive repair businesses routinely followed the practice of attempting to sell
customers unnecessary parts and services.

How would this behavior affect customers? How might customers attempt to protect themselves against this behavior?
How would this behavior probably affect profits and employment in the automotive service
industry?
EXERCISE 1–8 Cognitive Bias
In the 1970s, one million college-bound students were surveyed and asked to compare themselves
to their peers. Some of the key findings of the survey were as follows:
a. 70% of the students rated themselves as above average in leadership ability, while only 2%
rated themselves as below average in this regard.
b. With respect to athletic skills, 60% of the students rated their skills as above the median and
only 6% of students rated themselves as below the median.
c. 60% of the students rated themselves in the top 10% in terms of their ability to get along with
others, while 25% of the students felt that they were in the top 1% in terms of this interpersonal skill.
Required:
What type of cognitive bias reveals itself in the data mentioned above? How might this cognitive
bias adversely influence a manager’s planning, controlling, and decision-making activities? What
steps could managers take to reduce the possibility that this cognitive bias would adversely influence their actions?

EXERCISE 1–9 Ethics and Decision Making
Assume that you are the chairman of the Department of Accountancy at Mountain State University.
One of the accounting professors in your department, Dr. Candler, has been consistently and uniformly regarded by students as an awful teacher for more than 10 years. Other accounting professors within your department have observed Dr. Candler’s classroom teaching and they concur that
his teaching skills are very poor. However, Dr. Candler was granted tenure 12 years ago, thereby
ensuring him life-long job security at Mountain State University.

Much to your surprise, today you received a phone from an accounting professor at Oregon
Coastal University. During this phone call you are informed that Oregon Coastal University is on
the verge of making a job offer to Dr. Candler. However, before extending the job offer, the faculty
at Oregon Coastal wants your input regarding Dr. Candler’s teaching effectiveness while at Mountain State University.
Required:
How would you respond to the professor from Oregon Coastal University? What would you say
about Dr. Candler’s teaching ability? Would you describe your answer to this inquiry as being ethical? Why?
EXERCISE 1–10 Corporate Social Responsbility
In his book Capitalism and Freedom, economist Milton Friedman wrote on page 133: “There is
one and only one social responsibility of business—to use its resources and engage in activities
designed to increase its profits so long as it . . . engages in open and free competition, without
deception or fraud.”
Required:
Explain why you agree or disagree with this quote.
EXERCISE 1–11 Intrinsic Motivation and Extrinsic Incentives
In a Harvard Business Review article titled “Why Incentive Plans Cannot Work,” (Volume 71, Issue 5)
author Alfie Kohn wrote: “Research suggests that, by and large, rewards succeed at securing one
thing only: temporary compliance. When it comes to producing lasting change in attitudes and
behavior, however, rewards, like punishment, are strikingly ineffective. Once the rewards run out,
people revert to their old behaviors. . . . Incentives, a version of what psychologists call extrinsic
motivators, do not alter the attitudes that underlie our behaviors. They do not create an enduring commitment to any value or action. Rather, incentives merely—and temporarily—change what we do.”

Do you agree with this quote? Why?
As a manager, how would you seek to motivate your employees?
As a manager, would you use financial incentives to compensate your employees? If so, what
would be the keys to using them effectively? If not, then how would you compensate your
employees?
EXERCISE 1–12 Cognitive Bias and Decision Making
During World War II, the U.S. military was studying its combat-tested fighter planes to determine
the parts of the plane that were most vulnerable to enemy fire. The purpose of the study was to
identify the most vulnerable sections of each plane and then take steps to reinforce those sections
to improve pilot safety and airplane durability. The data gathered by the U.S. military showed that
certain sections of its combat-tested fighter planes were consistently hit more often with enemy
fire than other sections of the plane.

EXERCISE 1–13 Ethics and Decision Making
Assume that you just completed a December weekend vacation to a casino within the United
States. During your trip you won $10,000 gambling. When the casino exchanged your chips for
cash they did not record any personal information, such as your driver’s license number or social
security number. Four months later while preparing your tax returns for the prior year, you stop to
contemplate the fact that the Internal Revenue Service requires taxpayers to report all gambling
winnings on Form 1040.
Required:
Would you report your gambling winnings to the Internal Revenue Service so that you could pay
federal income taxes on those winnings? Do you believe that your actions are ethical? Why?
Managerial Accounting: An Overview
Appendix 1A: Corporate Governance
Effective corporate governance enhances stockholders’ confidence that a company is
being run in their best interests rather than in the interests of top managers. Corporate
governance is the system by which a company is directed and controlled. If properly
implemented, the corporate governance system should provide incentives for the board
of directors and top management to pursue objectives that are in the interests of the company’s owners and it should provide for effective monitoring of performance.1
Unfortunately, history has repeatedly shown that unscrupulous top managers, if
unchecked, can exploit their power to defraud stockholders. This unpleasant reality
became all too clear in 2001 when the fall of Enron kicked off a wave of corporate
scandals. These scandals were characterized by financial reporting fraud and misuse of
corporate funds at the very highest levels—including CEOs and CFOs. While this was
disturbing in itself, it also indicated that the institutions intended to prevent such abuses
weren’t working, thus raising fundamental questions about the adequacy of the existing
corporate governance system. In an attempt to respond to these concerns, the U.S. Congress passed the most important reform of corporate governance in many decades—The
Sarbanes-Oxley Act of 2002.
The Sarbanes-Oxley Act of 2002
The Sarbanes-Oxley Act of 2002 was intended to protect the interests of those who
invest in publicly traded companies by improving the reliability and accuracy of corporate financial reports and disclosures. We would like to highlight six key aspects of the
legislation.2
First, the Act requires that both the CEO and CFO certify in writing that their company’s financial statements and accompanying disclosures fairly represent the results of
operations—with possible jail time if a CEO or CFO certifies results that they know
are false. This creates very powerful incentives for the CEO and CFO to ensure that the
financial statements contain no misrepresentations.
Second, the Act established the Public Company Accounting Oversight Board to provide additional oversight over the audit profession. The Act authorizes the Board to conduct investigations, to take disciplinary actions against audit firms, and to enact various
standards and rules concerning the preparation of audit reports.
Third, the Act places the power to hire, compensate, and terminate the public
accounting firm that audits a company’s financial reports in the hands of the audit
committee of the board of directors. Previously, management often had the power to
hire and fire its auditors. Furthermore, the Act specifies that all members of the audit
committee must be independent, meaning that they do not have an affiliation with the
company they are overseeing, nor do they receive any consulting or advisory compensation from the company.
Fourth, the Act places important restrictions on audit firms. Historically, public
accounting firms earned a large part of their profits by providing consulting services to
the companies that they audited. This provided the appearance of a lack of independence
because a client that was dissatisfied with an auditor’s stance on an accounting issue
might threaten to stop using the auditor as a consultant. To avoid this possible conflict
of interests, the Act prohibits a public accounting firm from providing a wide variety of
nonauditing services to an audit client.
Fifth, the Act requires that a company’s annual report contain an internal control
report. Internal controls are put in place by management to provide assurance to investors that financial disclosures are reliable. The report must state that it is management’s

Corporate Governance published by the Organization for Economic Co-Operation and Development.

responsibility to establish and maintain adequate internal controls and it must contain
an assessment by management of the effectiveness of its internal control structure. The
internal control report is accompanied by an opinion from the company’s audit firm
as to whether management has maintained effective internal control over its financial
reporting process.
Finally, the Act establishes severe penalties of as many as 20 years in prison for
altering or destroying any documents that may eventually be used in an official proceeding and as many as 10 years in prison for managers who retaliate against a so-called
whistle-blower who goes outside the chain of command to report misconduct. Collectively, these six aspects of the Sarbanes-Oxley Act of 2002 were intended to help reduce
the incidence of fraudulent financial reporting.
Internal Control—A Closer Look
Internal control is an important concept for all managers to understand and, although
you may not be aware of it, it also plays an important role in your personal life. Internal
control is a process designed to provide reasonable assurance that objectives are being
achieved. For example, one objective for your personal life is to live to a ripe old age.
Unfortunately, there are risks that we all encounter that may prohibit us from achieving
this objective. For example, we may die prematurely due to a heart attack, a car accident,
or a house fire. To reduce the risk of these unfortunate events occurring, we implement
controls in our lives. We may exercise regularly and make nutritional food choices to
reduce the likelihood of a heart attack. We always wear seat belts and instruct our friends
to prohibit us from drinking alcohol and driving a vehicle to reduce the risk of a fatal car
crash. We install fire detectors in our homes to reduce the risk of a fatal fire. In short,
internal controls are an integral part of our daily lives.
A company uses internal controls to provide reasonable assurance that its financial
reports are reliable.3 Its financial statements may contain intentional or unintentional
errors for three reasons. First, the statements may erroneously exclude some transactions.
For example, the income statement may fail to include legitimate expenses. Second, the
statements may improperly include some transactions. For example, the income statement may include sales revenue that was not earned during the current period. Third, the
statements may include transactions that have been recorded erroneously. For example,
an expense or sales transaction may be recorded at the wrong amount.
Exhibit 1A–1 describes seven types of internal controls that companies use to reduce
the risk that these types of errors will occur. Each item in the exhibit is labeled as a
preventive control and/or a detective control. A preventive control deters undesirable
events from occurring. A detective control detects undesirable events that have already
occurred. Requiring authorizations for certain types of transactions is a preventive control. For example, companies frequently require that a specific senior manager sign all
checks above a particular dollar amount to reduce the risk of an inappropriate cash disbursement. Reconciliations are a detective control. If you have ever compared a bank
statement to your checkbook to resolve any discrepancies, then you have performed a
type of reconciliation known as a bank reconciliation. This is a detective control because
you are seeking to identify any mistakes already made by the bank or existing mistakes
in your own records.
Segregation of duties is a preventive control that separates responsibilities for authorizing transactions, recording transactions, and maintaining custody of the related assets.
For example, the same employee should not have the ability to authorize inventory
purchases, account for those purchases, and manage the inventory storeroom. Physical
safeguards prevent unauthorized employees from having access to assets such as inventories and computer equipment. Performance reviews are a detective control performed

Companies also use internal controls to achieve efficient and effective operations and to ensure compliance with applicable laws and regulations.

by employees in supervisory positions to ensure that actual results are reasonable when
compared to relevant benchmarks. If actual results unexpectedly deviate from expectations, then it triggers further analysis to determine the root cause of the deviation. Companies maintain records to provide evidence that supports each transaction. For example,
companies use serially numbered checks so that they can readily track all of their cash
disbursements. Finally, companies use passwords (a preventive control) and access logs
(a detective control) to restrict electronic data access as appropriate.
It is important to understand that internal controls cannot guarantee that objectives
will be achieved. For example, a person can regularly exercise and eat healthy foods, but
this does not guarantee that they will live to a certain age. Similarly, an effective internal control system can provide reasonable assurance that financial statement disclosures
are reliable, but it cannot offer guarantees because even a well-designed internal control
system can break down. Furthermore, two or more employees may collude to circumvent
the control system. Finally, a company’s senior leaders may manipulate financial results
by intentionally overriding prescribed policies and procedures. This reality highlights the
importance of having senior leaders (including the chief executive officer, the chief financial officer, and the audit committee of the board of directors) who value the importance
of effective internal controls and are committed to creating an ethical “tone at the top” of
the organization.

room throughout their recovery, only the gear and staff are in motion. As
the patient’s condition stabilizes, the beeping machines of intensive care are
removed and physical therapy equipment is added.” The results of this shift
in orientation have been impressive. Patient satisfaction scores have skyrocketed and the average length of a patient’s stay in the hospital has declined by

Chapter 2
his chapter explains that in managerial accounting the term
cost is used in many different ways. The reason is that there are many types of
costs, and these costs are classified differently according to the immediate needs
of management. For example, managers may want cost data to prepare external
financial reports, to prepare planning budgets, or to make decisions. Each different use
of cost data demands a different classification and definition of costs. For example, the
preparation of external financial reports requires the use of historical cost data, whereas
decision making may require predictions about future costs. This notion of different costs
for different purposes is a critically important aspect of managerial accounting.
Exhibit 2–1 summarizes the cost classifications that will be defined in this chapter,
namely cost classifications (1) for assigning costs to cost objects, (2) for manufacturing
companies, (3) for preparing financial statements, (4) for predicting cost behavior, and
(5) for making decisions. As we begin defining the cost terminology related to each of
these cost classifications, please refer back to this exhibit to help improve your understanding of the overall organization of the chapter.

Understand cost classifications
used for assigning costs to
cost objects: direct costs and
indirect costs.
Costs are assigned to cost objects for a variety of purposes including pricing, preparing profitability studies, and controlling spending. A cost object is anything for which
cost data are desired—including products, customers, jobs, and organizational subunits.
For purposes of assigning costs to cost objects, costs are classified as either direct or
indirect.
Direct Cost
A direct cost is a cost that can be easily and conveniently traced to a specified cost
object. For example, if Reebok is assigning costs to its various regional and national
sales offices, then the salary of the sales manager in its Tokyo office would be a direct

cost of that office. If a printing company made 10,000 brochures for a specific
customer, then the cost of the paper used to make the brochures would be a direct cost of
that customer.
Indirect Cost
An indirect cost is a cost that cannot be easily and conveniently traced to a specified cost
object. For example, a Campbell Soup factory may produce dozens of varieties of canned
soups. The factory manager’s salary would be an indirect cost of a particular variety such
as chicken noodle soup. The reason is that the factory manager’s salary is incurred as a
consequence of running the entire factory—it is not incurred to produce any one soup
variety. To be traced to a cost object such as a particular product, the cost must be caused
by the cost object. The factory manager’s salary is called a common cost of producing
the various products of the factory. A common cost is a cost that is incurred to support a
number of cost objects but cannot be traced to them individually. A common cost is a type
of indirect cost.
A particular cost may be direct or indirect, depending on the cost object. While the
Campbell Soup factory manager’s salary is an indirect cost of manufacturing chicken
noodle soup, it is a direct cost of the manufacturing division. In the first case, the cost
object is chicken noodle soup. In the second case, the cost object is the entire manufacturing division.
Cost Classifications for Manufacturing Companies
Manufacturing companies such as Texas Instruments, Ford, and DuPont separate their
costs into two broad categories—manufacturing and nonmanufacturing costs.
Manufacturing Costs
Most manufacturing companies further separate their manufacturing costs into two direct
cost categories, direct materials and direct labor, and one indirect cost category, manufacturing overhead. A discussion of each of these categories follows.
Direct Materials The materials that go into the final product are called raw
materials. This term is somewhat misleading because it seems to imply unprocessed natural resources like wood pulp or iron ore. Actually, raw materials refer to any materials
that are used in the final product; and the finished product of one company can become
the raw materials of another company. For example, the plastics produced by Du Pont
are a raw material used by Hewlett-Packard in its personal computers.
Raw materials may include both direct and indirect materials. Direct materials are
those materials that become an integral part of the finished product and whose costs can
be conveniently traced to the finished product. This would include, for example, the seats
that Airbus purchases from subcontractors to install in its commercial aircraft and the
electronic components that Apple uses in its iPhones.
Sometimes it isn’t worth the effort to trace the costs of relatively insignificant materials to end products. Such minor items would include the solder used to make electrical
connections in a Sony HDTV or the glue used to assemble an Ethan Allen chair. Materials such as solder and glue are called indirect materials and are included as part of
manufacturing overhead, which is discussed shortly.
Direct Labor Direct labor consists of labor costs that can be easily (i.e., physically
and conveniently) traced to individual units of product. Direct labor is sometimes called
touch labor because direct labor workers typically touch the product while it is being
made. Examples of direct labor include assembly-line workers at Toyota, carpenters

FOOD PRICES HIT RECORD HIGHS FOR RESTAURANTS
Direct material costs are critically important to restaurants and fast-food chains. In recent years,
some food costs have spiked to record highs. For example, unexpected freezing temperatures
in the southwestern portion of the United States caused the cost of lettuce to increase 290%.
Similarly, the costs of green peppers, tomatoes, and cucumbers jumped 145%, 85%, and 30%,
respectively. A large chain such as Subway can withstand these price increases better than smaller
competitors because of its buying power and long-term contracts.

at the home builder KB Home, and electricians who install equipment on aircraft at
Bombardier Learjet.
Labor costs that cannot be physically traced to particular products, or that can be
traced only at great cost and inconvenience, are termed indirect labor. Just like indirect materials, indirect labor is treated as part of manufacturing overhead. Indirect labor
includes the labor costs of janitors, supervisors, materials handlers, and night security
guards. Although the efforts of these workers are essential, it would be either impractical or impossible to accurately trace their costs to specific units of product. Hence, such
labor costs are treated as indirect labor.
Manufacturing Overhead Manufacturing overhead, the third manufacturing
cost category, includes all manufacturing costs except direct materials and direct labor.
Manufacturing overhead includes items such as indirect materials; indirect labor; maintenance and repairs on production equipment; and heat and light, property taxes, depreciation, and insurance on manufacturing facilities. A company also incurs costs for heat
and light, property taxes, insurance, depreciation, and so forth, associated with its selling
and administrative functions, but these costs are not included as part of manufacturing
overhead. Only those costs associated with operating the factory are included in manufacturing overhead.
Various names are used for manufacturing overhead, such as indirect manufacturing
cost, factory overhead, and factory burden. All of these terms are synonyms for manufacturing overhead.
Nonmanufacturing Costs
Nonmanufacturing costs are often divided into two categories: (1) selling costs and
(2) administrative costs. Selling costs include all costs that are incurred to secure customer orders and get the finished product to the customer. These costs are sometimes
called order-getting and order-filling costs. Examples of selling costs include advertising, shipping, sales travel, sales commissions, sales salaries, and costs of finished goods
warehouses. Selling costs can be either direct or indirect costs. For example, the cost of
an advertising campaign dedicated to one specific product is a direct cost of that product,
whereas the salary of a marketing manager who oversees numerous products is an indirect cost with respect to individual products.
Administrative costs include all costs associated with the general management
of an organization rather than with manufacturing or selling. Examples of administrative costs include executive compensation, general accounting, secretarial, public relations, and similar costs involved in the overall, general administration of the
organization as a whole. Administrative costs can be either direct or indirect costs.
For example, the salary of an accounting manager in charge of accounts receivable
collections in the East region is a direct cost of that region, whereas the salary of a
Managerial Accounting and Cost Concepts
31
chief financial officer who oversees all of a company’s regions is an indirect cost with
respect to individual regions.
Nonmanufacturing costs are also often called selling, general, and administrative
(SG&A) costs or just selling and administrative costs.
Cost Classifications for Preparing Financial Statements
When preparing a balance sheet and an income statement, companies need to classify
their costs as product costs or period costs. To understand the difference between product costs and period costs, we must first discuss the matching principle from financial
accounting.
Generally, costs are recognized as expenses on the income statement in the period
that benefits from the cost. For example, if a company pays for liability insurance in
advance for two years, the entire amount is not considered an expense of the year in which
the payment is made. Instead, one-half of the cost would be recognized as an expense
each year. The reason is that both years—not just the first year—benefit from the insurance payment. The unexpensed portion of the insurance payment is carried on the balance
sheet as an asset called prepaid insurance.
The matching principle is based on the accrual concept that costs incurred to generate a particular revenue should be recognized as expenses in the same period that the
revenue is recognized. This means that if a cost is incurred to acquire or make something
that will eventually be sold, then the cost should be recognized as an expense only when
the sale takes place—that is, when the benefit occurs. Such costs are called product costs.
Product Costs
For financial accounting purposes, product costs include all costs involved in acquiring
or making a product. In the case of manufactured goods, these costs consist of direct
materials, direct labor, and manufacturing overhead.1 Product costs “attach” to units of
product as the goods are purchased or manufactured, and they remain attached as the
goods go into inventory awaiting sale. Product costs are initially assigned to an inventory
account on the balance sheet. When the goods are sold, the costs are released from inventory as expenses (typically called cost of goods sold) and matched against sales revenue
on the income statement. Because product costs are initially assigned to inventories, they
are also known as inventoriable costs.
We want to emphasize that product costs are not necessarily recorded as expenses
on the income statement in the period in which they are incurred. Rather, as explained
above, they are recorded as expenses in the period in which the related products are sold.
Period Costs
Period costs are all the costs that are not product costs. All selling and administrative
expenses are treated as period costs. For example, sales commissions, advertising, executive salaries, public relations, and the rental costs of administrative offices are all period
costs. Period costs are not included as part of the cost of either purchased or manufactured goods; instead, period costs are expensed on the income statement in the period in
which they are incurred using the usual rules of accrual accounting. Keep in mind that
the period in which a cost is incurred is not necessarily the period in which cash changes
hands. For example, as discussed earlier, the costs of liability insurance are spread across
the periods that benefit from the insurance—regardless of the period in which the insurance premium is paid.

For internal management purposes, product costs may exclude some manufacturing costs. For example, see Appendix 3A and the discussion in Chapter 6.

Chapter 2
Prime Cost and Conversion Cost
Two more cost categories are often used in discussions of manufacturing costs—prime
cost and conversion cost. Prime cost is the sum of direct materials cost and direct labor
cost. Conversion cost is the sum of direct labor cost and manufacturing overhead cost.
The term conversion cost is used to describe direct labor and manufacturing overhead
because these costs are incurred to convert materials into the finished product.
To improve your understanding of these definitions, consider the following scenario:
A company has reported the following costs and expenses for the most recent month:
Direct materials . . . . . . . . . . . . . . . . . . . . .

costs, period costs, conversion costs, and prime costs:

WALMART LOOKS TO REDUCE ITS SHIPPING COSTS
Walmart hopes to lower its shipping costs, thereby enabling it to reduce its “everyday low prices.”
In years past, suppliers would ship their merchandise to Walmart’s distribution centers, and then
Walmart would use its own fleet of trucks to ship goods from its distribution centers to its retail
store locations. However, now Walmart wants to assume control of transporting merchandise
from its suppliers’ manufacturing facilities to its distribution centers. Walmart believes it can
lower these shipping costs by carrying more merchandise per truck and by taking advantage of
volume purchase price discounts for fuel. In exchange for assuming these shipping responsibilities, Walmart is seeking price reductions from suppliers that it can pass along, at least in part,
to its customers.

Cost Classifications for Predicting Cost Behavior
It is often necessary to predict how a certain cost will behave in response to a change in activity. For example, a manager at Under Armour may want to estimate the impact a 5 percent
increase in sales would have on the company’s total direct materials cost. Cost behavior
refers to how a cost reacts to changes in the level of activity. As the activity level rises and
falls, a particular cost may rise and fall as well—or it may remain constant. For planning
purposes, a manager must be able to anticipate which of these will happen; and if a cost
can be expected to change, the manager must be able to estimate how much it will change.
To help make such distinctions, costs are often categorized as variable, fixed, or mixed. The
relative proportion of each type of cost in an organization is known as its cost structure.
For example, an organization might have many fixed costs but few variable or mixed costs.
Alternatively, it might have many variable costs but few fixed or mixed costs.
LO2–4
Understand cost classifications
used to predict cost behavior:
variable costs, fixed costs, and
mixed costs.
Variable Cost
A variable cost varies, in total, in direct proportion to changes in the level of activity.
Common examples of variable costs include cost of goods sold for a merchandising company, direct materials, direct labor, variable elements of manufacturing overhead, such as
indirect materials, supplies, and power, and variable elements of selling and administrative expenses, such as commissions and shipping costs.2
For a cost to be variable, it must be variable with respect to something. That “something” is its activity base. An activity base is a measure of whatever causes the incurrence
of a variable cost. An activity base is sometimes referred to as a cost driver. Some of the
most common activity bases are direct labor-hours, machine-hours, units produced, and
units sold. Other examples of activity bases (cost drivers) include the number of miles
driven by salespersons, the number of pounds of laundry cleaned by a hotel, the number
of calls handled by technical support staff at a software company, and the number of beds
occupied in a hospital. While there are many activity bases within organizations, throughout this textbook, unless stated otherwise, you should assume that the activity base under
consideration is the total volume of goods and services provided by the organization. We
will specify the activity base only when it is something other than total output.
To provide an example of a variable cost, consider Nooksack Expeditions, a small
company that provides daylong whitewater rafting excursions on rivers in the North
COST DRIVERS IN THE ELECTRONICS INDUSTRY
Accenture Ltd. estimates that the U.S. electronics industry spends $13.8 billion annually to rebox,
restock, and resell returned products. Conventional wisdom is that customers only return products
when they are defective, but the data show that this explanation only accounts for 5% of customer
returns. The biggest cost drivers that cause product returns are that customers often inadvertently
buy the wrong products and that they cannot understand how to use the products that they have
purchased. Television manufacturer Vizio Inc. has started including more information on its packaging to help customers avoid buying the wrong product. Seagate Technologies is replacing thick
instruction manuals with simpler guides that make it easier for customers to begin using their
products.

Direct labor costs often can be fixed instead of variable for a variety of reasons. For example, in some
countries, such as France, Germany, and Japan, labor regulations and cultural norms may limit management’s ability to adjust the labor force in response to changes in activity. In this textbook, always assume
that direct labor is a variable cost unless you are explicitly told otherwise.

The Sporthotel Theresa (http://www.theresa.at/), owned and operated by the Egger family, is a four
star hotel located in Zell im Zillertal, Austria. The hotel features access to hiking, skiing, biking, and
other activities in the Ziller alps as well as its own fitness facility and spa.
Three full meals a day are included in the hotel room charge. Breakfast and lunch are served
buffet-style while dinner is a more formal affair with as many as six courses. The chef, Stefan Egger,
believes that food costs are roughly proportional to the number of guests staying at the hotel; that
is, they are a variable cost. He must order food from suppliers two or three days in advance, but
he adjusts his purchases to the number of guests who are currently staying at the hotel and their
consumption patterns. In addition, guests make their selections from the dinner menu early in the
day, which helps Stefan plan which foodstuffs will be required for dinner. Consequently, he is able to
prepare just enough food so that all guests are satisfied and yet waste is held to a minimum.

Cascade Mountains. The company provides all of the necessary equipment and experienced guides, and it serves gourmet meals to its guests. The meals are purchased from a
caterer for $30 a person for a daylong excursion. The behavior of this variable cost, on
both a per unit and a total basis, is shown below:

While total variable costs change as the activity level changes, it is important to note
that a variable cost is constant if expressed on a per unit basis. For example, the per unit
cost of the meals remains constant at $30 even though the total cost of the meals increases
and decreases with activity. The graph on the left-hand side of Exhibit 2–2 illustrates that
the total variable cost rises and falls as the activity level rises and falls. At an activity level
of 250 guests, the total meal cost is $7,500. At an activity level of 1,000 guests, the total
meal cost rises to $30,000.
Fixed Cost
A fixed cost is a cost that remains constant, in total, regardless of changes in the level of
activity. Examples of fixed costs include straight-line depreciation, insurance, property
taxes, rent, supervisory salaries, administrative salaries, and advertising. Unlike variable
costs, fixed costs are not affected by changes in activity. Consequently, as the activity
level rises and falls, total fixed costs remain constant unless influenced by some outside force, such as a landlord increasing your monthly rental expense. To continue the
Nooksack Expeditions example, assume the company rents a building for $500 per
month to store its equipment. The total amount of rent paid is the same regardless of
the number of guests the company takes on its expeditions during any given month. The
concept of a fixed cost is shown graphically on the right-hand side of Exhibit 2–2.
Because total fixed costs remain constant for large variations in the level of activity, the average fixed cost per unit becomes progressively smaller as the level of activity increases. If Nooksack Expeditions has only 250 guests in a month, the $500 fixed
rental cost would amount to an average of $2 per guest. If there are 1,000 guests, the
fixed rental cost would average only 50 cents per guest. The table below illustrates

As a general rule, we caution against expressing fixed costs on an average per unit
basis in internal reports because it creates the false impression that fixed costs are like
variable costs and that total fixed costs actually change as the level of activity changes.
For planning purposes, fixed costs can be viewed as either committed or discretionary. Committed fixed costs represent organizational investments with a multiyear planning horizon that can’t be significantly reduced even for short periods of time without
making fundamental changes. Examples include investments in facilities and equipment,
as well as real estate taxes, insurance expenses, and salaries of top management. Even if
operations are interrupted or cut back, committed fixed costs remain largely unchanged
in the short term because the costs of restoring them later are likely to be far greater than
any short-run savings that might be realized. Discretionary fixed costs (often referred
to as managed fixed costs) usually arise from annual decisions by management to spend
on certain fixed cost items. Examples of discretionary fixed costs include advertising,
research, public relations, management development programs, and internships for students. Discretionary fixed costs can be cut for short periods of time with minimal damage
to the long-run goals of the organization.
The Linearity Assumption and the Relevant Range
Management accountants ordinarily assume that costs are strictly linear; that is, the relation between cost on the one hand and activity on the other can be represented by a
straight line. Economists point out that many costs are actually curvilinear; that is, the
relation between cost and activity is a curve. Nevertheless, even if a cost is not strictly

linear, it can be approximated within a narrow band of activity known as the relevant
range by a straight line. The relevant range is the range of activity within which the
assumption that cost behavior is strictly linear is reasonably valid. Outside of the relevant
range, a fixed cost may no longer be strictly fixed or a variable cost may not be strictly
variable. Managers should always keep in mind that assumptions made about cost behavior may be invalid if activity falls outside of the relevant range.
The concept of the relevant range is important in understanding fixed costs. For
example, suppose the Mayo Clinic rents a machine for $20,000 per month that tests
blood samples for the presence of leukemia cells. Furthermore, suppose that the capacity of the leukemia diagnostic machine is 3,000 tests per month. The assumption that
the rent for the diagnostic machine is $20,000 per month is only valid within the relevant range of 0 to 3,000 tests per month. If the Mayo Clinic needed to test 5,000 blood
samples per month, then it would need to rent another machine for an additional $20,000
per month. It would be difficult to rent half of a diagnostic machine; therefore, the step
pattern depicted in Exhibit 2–3 is typical for such costs. This exhibit shows that the
fixed rental expense is $20,000 for a relevant range of 0 to 3,000 tests. The fixed rental
expense increases to $40,000 within the relevant range of 3,001 to 6,000 tests. The rental
expense increases in discrete steps or increments of 3,000 tests, rather than increasing in
a linear fashion per test.
This step-oriented cost behavior pattern can also be used to describe other costs,
such as some labor costs. For example, salaried employee expenses can be characterized
using a step pattern. Salaried employees are paid a fixed amount, such as $40,000 per
year, for providing the capacity to work a prespecified amount of time, such as 40 hours
per week for 50 weeks a year (5 2,000 hours per year). In this example, the total salaried
employee expense is $40,000 within a relevant range of 0 to 2,000 hours of work. The
total salaried employee expense increases to $80,000 (or two employees) if the organization’s work requirements expand to a relevant range of 2,001 to 4,000 hours of work. Cost
behavior patterns such as salaried employees are often called step-variable costs. Stepvariable costs can often be adjusted quickly as conditions change. Furthermore, the width
of the steps for step-variable costs is generally so narrow that these costs can be treated
essentially as variable costs for most purposes. The width of the steps for fixed costs, on
the other hand, is so wide that these costs should be treated as entirely fixed within the
relevant range.

HOW MANY GUIDES?
Majestic Ocean Kayaking, of Ucluelet, British Columbia, is owned and operated by Tracy Morben-Eeftink. The company offers a number of guided kayaking excursions ranging from threehour tours of the Ucluelet harbor to six-day kayaking and camping trips in Clayoquot Sound.
One of the company’s excursions is a four-day kayaking and camping trip to The Broken Group
Islands in the Pacific Rim National Park. Special regulations apply to trips in the park—including a requirement that one certified guide must be assigned for every five guests or fraction
thereof. For example, a trip with 12 guests must have at least three certified guides. Guides
are not salaried and are paid on a per-day basis. Therefore, the cost to the company of the
guides for a trip is a step-variable cost rather than a fixed cost or a strictly variable cost. One
guide is needed for 1 to 5 guests, two guides for 6 to 10 guests, three guides for 11 to 15
guests, and so on.

Mixed Costs
A mixed cost contains both variable and fixed cost elements. Mixed costs are also known
as semivariable costs. To continue the Nooksack Expeditions example, the company
incurs a mixed cost called fees paid to the state. It includes a license fee of $25,000 per
year plus $3 per rafting party paid to the state’s Department of Natural Resources. If the
company runs 1,000 rafting parties this year, then the total fees paid to the state would
be $28,000, made up of $25,000 in fixed cost plus $3,000 in variable cost. Exhibit 2–5
depicts the behavior of this mixed cost.
Even if Nooksack fails to attract any customers, the company will still have to
pay the license fee of $25,000. This is why the cost line in Exhibit 2–5 intersects
the vertical cost axis at the $25,000 point. For each rafting party the company organizes, the total cost of the state fees will increase by $3. Therefore, the total cost line
slopes upward as the variable cost of $3 per party is added to the fixed cost of $25,000
per year.
Because the mixed cost in Exhibit 2–5 is represented by a straight line, the following
equation for a straight line can be used to express the relationship between a mixed cost
and the level of activity:

This equation makes it easy to calculate the total mixed cost for any level of activity

follows:
Y 5 $25,000 1 ($3.00 per rafting party 3 800 rafting parties)

The Analysis of Mixed Costs
Mixed costs are very common. For example, the overall cost of providing X-ray services
to patients at the Harvard Medical School Hospital is a mixed cost. The costs of equipment depreciation and radiologists’ and technicians’ salaries are fixed, but the costs of
X-ray film, power, and supplies are variable. At Southwest Airlines, maintenance costs
Managerial Accounting and Cost Concepts
39
are a mixed cost. The company incurs fixed costs for renting maintenance facilities and
for keeping skilled mechanics on the payroll, but the costs of replacement parts, lubricating oils, tires, and so forth, are variable with respect to how often and how far the company’s aircraft are flown.
The fixed portion of a mixed cost represents the minimum cost of having a service
ready and available for use. The variable portion represents the cost incurred for actual
consumption of the service, thus it varies in proportion to the amount of service actually
consumed.
Managers can use a variety of methods to estimate the fixed and variable components of a mixed cost such as account analysis, the engineering approach, the high-low
method, and least-squares regression analysis. In account analysis, an account is classified as either variable or fixed based on the analyst’s prior knowledge of how the cost in
the account behaves. For example, direct materials would be classified as variable and a
building lease cost would be classified as fixed because of the nature of those costs. The
engineering approach to cost analysis involves a detailed analysis of what cost behavior
should be, based on an industrial engineer’s evaluation of the production methods to be
used, the materials specifications, labor requirements, equipment usage, production efficiency, power consumption, and so on.
The high-low and least-squares regression methods estimate the fixed and variable
elements of a mixed cost by analyzing past records of cost and activity data. We will use
an example from Brentline Hospital to illustrate the high-low method calculations and
to compare the resulting high-low method cost estimates to those obtained using leastsquares regression. Appendix 2A demonstrates how to use Microsoft Excel to perform
least-squares regression computations.
Diagnosing Cost Behavior with a Scattergraph Plot
Assume that Brentline Hospital is interested in predicting future monthly maintenance
costs for budgeting purposes. The senior management team believes that maintenance
cost is a mixed cost and that the variable portion of this cost is driven by the number
of patient-days. Each day a patient is in the hospital counts as one patient-day. The
hospital’s chief financial officer gathered the following data for the most recent sevenmonth period:
Month
January . . . . . .
February . . . . . .
March . . . . . . . .
April . . . . . . . .
May . . . . . . . . .

$9,100
$9,800
$7,800
The first step in applying the high-low method or the least-squares regression method
is to diagnose cost behavior with a scattergraph plot. The scattergraph plot of maintenance costs versus patient-days at Brentline Hospital is shown in Exhibit 2–6. Two things
should be noted about this scattergraph:
1. The total maintenance cost, Y, is plotted on the vertical axis. Cost is known as the
dependent variable because the amount of cost incurred during a period depends on
the level of activity for the period. (That is, as the level of activity increases, total cost
will also ordinarily increase.)

2. The activity, X (patient-days in this case), is plotted on the horizontal axis. Activity is
known as the independent variable because it causes variations in the cost.
From the scattergraph plot, it is evident that maintenance costs do increase with the number of patient-days in an approximately linear fashion. In other words, the points lie
more or less along a straight line that slopes upward and to the right. Cost behavior is
considered linear whenever a straight line is a reasonable approximation for the relation
between cost and activity.
Plotting the data on a scattergraph is an essential diagnostic step that should be performed before performing the high-low method or least-squares regression calculations.
If the scattergraph plot reveals linear cost behavior, then it makes sense to perform the
high-low or least-squares regression calculations to separate the mixed cost into its variable and fixed components. If the scattergraph plot does not depict linear cost behavior,
then it makes no sense to proceed any further in analyzing the data.
The High-Low Method
Assuming that the scattergraph plot indicates a linear relation between cost and activity,
the fixed and variable cost elements of a mixed cost can be estimated using the high-low
method or the least-squares regression method. The high-low method is based on the
rise-over-run formula for the slope of a straight line. As previously discussed, if the relation between cost and activity can be represented by a straight line, then the slope of the
straight line is equal to the variable cost per unit of activity. Consequently, the following
formula can be used to estimate the variable cost:
Y2 2 Y1
Rise 5 _______
Variable cost 5 Slope of the line 5 ____
Run X2 2 X1
To analyze mixed costs with the high-low method, begin by identifying the period
with the lowest level of activity and the period with the highest level of activity. The
period with the lowest activity is selected as the first point in the above formula and
Managerial Accounting and Cost Concepts
the period with the highest activity is selected as the second point. Consequently, the
formula becomes:
Y22 Y1 Cost at the high activity level 2 Cost at the low activity level
Variable cost 5 _______ 5 _________________________________________________
X2 2 X1
High activity level 2 Low activity level
or
Change in cost
Variable cost 5 _______________
Change in activity
Therefore, when the high-low method is used, the variable cost is estimated by dividing
the difference in cost between the high and low levels of activity by the change in activity
between those two points.
To return to the Brentline Hospital example, using the high-low method, we first
identify the periods with the highest and lowest activity—in this case, June and March.
We then use the activity and cost data from these two periods to estimate the variable cost
component as follows:
High activity level (June) . . . . .
Low activity level (March) . . . .
Change . . . . . . . . . . . . . . . . . .

$2,400
Change in cost
$2,400
Variable cost 5 _______________ 5 _______________ 5 $0.80 per patient-day
Change in activity 3,000 patient-days
Having determined that the variable maintenance cost is 80 cents per patient-day,
we can now determine the amount of fixed cost. This is done by taking the total cost at
either the high or the low activity level and deducting the variable cost element. In the
computation below, total cost at the high activity level is used in computing the fixed
cost element:
Fixed cost element 5 Total cost 2 Variable cost element
5 $9,800 2 ($0.80 per patient-day 3 8,000 patient-days)
5 $3,400
Both the variable and fixed cost elements have now been isolated. The cost of maintenance can be expressed as $3,400 per month plus 80 cents per patient-day or as:
Y 5 $3,400 1 $0.80X

The data used in this illustration are shown graphically in Exhibit 2–7. Notice that a
straight line has been drawn through the points corresponding to the low and high levels
of activity. In essence, that is what the high-low method does—it draws a straight line
through those two points.
Sometimes the high and low levels of activity don’t coincide with the high and low
amounts of cost. For example, the period that has the highest level of activity may not

have the highest amount of cost. Nevertheless, the costs at the highest and lowest levels
of activity are always used to analyze a mixed cost under the high-low method. The reason is that the analyst would like to use data that reflect the greatest possible variation
in activity.
The high-low method is very simple to apply, but it suffers from a major (and
sometimes critical) defect—it utilizes only two data points. Generally, two data
points are not enough to produce accurate results. Additionally, the periods with the
highest and lowest activity tend to be unusual. A cost formula that is estimated solely
using data from these unusual periods may misrepresent the true cost behavior during
normal periods. Such a distortion is evident in Exhibit 2–7. The straight line should
probably be shifted down somewhat so that it is closer to more of the data points. For
these reasons, least-squares regression will generally be more accurate than the highlow method.
The Least-Squares Regression Method
The least-squares regression method, unlike the high-low method, uses all of the data
to separate a mixed cost into its fixed and variable components. A regression line of
the form Y 5 a 1 bX is fitted to the data, where a represents the total fixed cost and
b represents the variable cost per unit of activity. The basic idea underlying the leastsquares regression method is illustrated in Exhibit 2–8 using hypothetical data points.
Notice from the exhibit that the deviations from the plotted points to the regression line
are measured vertically on the graph. These vertical deviations are called the regression
errors. There is nothing mysterious about the least-squares regression method. It simply
computes the regression line that minimizes the sum of these squared errors. The formulas that accomplish this are fairly complex and involve numerous calculations, but the
principle is simple.

Fortunately, computers are adept at carrying out the computations required by the
least-squares regression formulas. The data—the observed values of X and Y—are
entered into the computer, and software does the rest. In the case of the Brentline Hospital maintenance cost data, a statistical software package on a personal computer can
calculate the following least-squares regression estimates of the total fixed cost (a) and
the variable cost per unit of activity (b):
a 5 $3,431
b 5 $0.759
Therefore, using the least-squares regression method, the fixed element of the maintenance cost is $3,431 per month and the variable portion is 75.9 cents per patient-day.
In terms of the linear equation Y 5 a 1 bX, the cost formula can be written as
Y 5 $3,431 1 $0.759X
where activity (X) is expressed in patient-days.
Appendix 2A discusses how to use Microsoft Excel to perform least-squares regression calculations. For now, you only need to understand that least-squares regression analysis generally provides more accurate cost estimates than the high-low method because,
rather than relying on just two data points, it uses all of the data points to fit a line that
minimizes the sum of the squared errors. The table below compares Brentline Hospital’s
cost estimates using the high-low method and the least-squares regression method:

When Brentline uses the least-squares regression method to create a straight line that
minimizes the sum of the squared errors, it results in estimated fixed costs that are $31
higher than the amount derived using the high-low method. It also decreases the slope
of the straight line resulting in a lower variable cost estimate of $0.759 per patient-day
rather than $0.80 per patient-day as derived using the high-low method.

Zipcar is a car sharing service based in Cambridge, Massachusetts. The company serves 13 cities
and 120 university campuses. Members pay a $50 annual fee plus $7 an hour to rent a car. They
can use their iPhones to rent a car, locate it in the nearest Zipcar parking lot, unlock it using an

Traditional and Contribution Format Income Statements

Prepare income statements
for a merchandising company
using the traditional and
contribution formats.
In this section of the chapter, we discuss how to prepare traditional and contribution format income statements for a merchandising company.3 Merchandising companies do
not manufacture the products that they sell to customers. For example, Lowe’s and
Home Depot are merchandising companies because they buy finished products from
manufacturers and then resell them to end consumers.
The Traditional Format Income Statement
Traditional income statements are prepared primarily for external reporting purposes.
The left-hand side of Exhibit 2–9 shows a traditional income statement format for
merchandising companies. This type of income statement organizes costs into two
categories—cost of goods sold and selling and administrative expenses. Sales minus cost
of goods sold equals the gross margin. The gross margin minus selling and administrative
expenses equals net operating income.
The cost of goods sold reports the product costs attached to the merchandise sold
during the period. The selling and administrative expenses report all period costs that
have been expensed as incurred. The cost of goods sold for a merchandising company

For example, let’s assume that the company depicted in Exhibit 2–9 purchased $3,000
of merchandise inventory during the period and had beginning and ending merchandise
inventory balances of $7,000 and $4,000, respectively. The equation above could be used
to compute the cost of goods sold as follows:

Although the traditional income statement is useful for external reporting purposes, it has serious limitations when used for internal purposes. It does not distinguish
between fixed and variable costs. For example, under the heading “Selling and administrative expenses,” both variable administrative costs ($400) and fixed administrative costs
($1,500) are lumped together ($1,900). Internally, managers need cost data organized by
cost behavior to aid in planning, controlling, and decision making. The contribution format income statement has been developed in response to these needs.
The Contribution Format Income Statement
The crucial distinction between fixed and variable costs is at the heart of the contribution
approach to constructing income statements. The unique thing about the contribution
approach is that it provides managers with an income statement that clearly distinguishes
between fixed and variable costs and therefore aids planning, controlling, and decision
making. The right-hand side of Exhibit 2–9 shows a contribution format income statement for merchandising companies.
The contribution approach separates costs into fixed and variable categories, first
deducting variable expenses from sales to obtain the contribution margin. For a merchandising company, cost of goods sold is a variable cost that gets included in the “Variable expenses” portion of the contribution format income statement. The contribution
margin is the amount remaining from sales revenues after variable expenses have been
deducted. This amount contributes toward covering fixed expenses and then toward
profits for the period.
The contribution format income statement is used as an internal planning and decision-making tool. Its emphasis on cost behavior aids cost-volume-profit analysis (such as
we shall be doing in a subsequent chapter), management performance appraisals, and
budgeting. Moreover, the contribution approach helps managers organize data pertinent
to numerous decisions such as product-line analysis, pricing, use of scarce resources, and
make or buy analysis. All of these topics are covered in later chapters.
Cost Classifications for Decision Making
Costs are an important feature of many business decisions. In making decisions, it is essential to have a firm grasp of the concepts differential cost, opportunity cost, and sunk cost.
Differential Cost and Revenue
Decisions involve choosing between alternatives. In business decisions, each alternative
will have costs and benefits that must be compared to the costs and benefits of the other
available alternatives. A difference in costs between any two alternatives is known as a

used in making decisions:
differential costs, opportunity
costs, and sunk costs.

Chapter 2
differential cost. A difference in revenues (usually just sales) between any two alternatives is known as differential revenue.
A differential cost is also known as an incremental cost, although technically an
incremental cost should refer only to an increase in cost from one alternative to another;
decreases in cost should be referred to as decremental costs. Differential cost is a broader
term, encompassing both cost increases (incremental costs) and cost decreases (decremental costs) between alternatives.
The accountant’s differential cost concept can be compared to the economist’s marginal cost concept. In speaking of changes in cost and revenue, the economist uses the
terms marginal cost and marginal revenue. The revenue that can be obtained from selling
one more unit of product is called marginal revenue, and the cost involved in producing
one more unit of product is called marginal cost. The economist’s marginal concept is basically the same as the accountant’s differential concept applied to a single unit of output.
Differential costs can be either fixed or variable. To illustrate, assume that Natural
Cosmetics, Inc., is thinking about changing its marketing method from distribution through
retailers to distribution by a network of neighborhood sales representatives. Present costs
and revenues are compared to projected costs and revenues in the following table:
Sales (Variable) . . . . . . . . . . . . . . . . . .
Cost of goods sold (Variable) . . . . . . .

According to the above analysis, the differential revenue is $100,000 and the differential
costs total $85,000, leaving a positive differential net operating income of $15,000 in
favor of using sales representatives.
In general, only the differences between alternatives are relevant in decisions. Those
items that are the same under all alternatives and that are not affected by the decision
can be ignored. For example, in the Natural Cosmetics, Inc., example above, the “Other
expenses” category, which is $60,000 under both alternatives, can be ignored because it
has no effect on the decision. If it were removed from the calculations, the sales representatives would still be preferred by $15,000. This is an extremely important principle in
management accounting that we will revisit in later chapters.
Opportunity Cost and Sunk Cost
Opportunity cost is the potential benefit that is given up when one alternative is selected
over another. For example, assume that you have a part-time job while attending college
that pays $200 per week. If you spend one week at the beach during spring break without
pay, then the $200 in lost wages would be an opportunity cost of taking the week off to
be at the beach. Opportunity costs are not usually found in accounting records, but they
are costs that must be explicitly considered in every decision a manager makes. Virtually
every alternative involves an opportunity cost.
A sunk cost is a cost that has already been incurred and that cannot be changed by
any decision made now or in the future. Because sunk costs cannot be changed by any
decision, they are not differential costs. And because only differential costs are relevant in
a decision, sunk costs should always be ignored.
Managerial Accounting and Cost Concepts
47
To illustrate a sunk cost, assume that a company paid $50,000 several years ago for
a special-purpose machine. The machine was used to make a product that is now obsolete and is no longer being sold. Even though in hindsight purchasing the machine may
have been unwise, the $50,000 cost has already been incurred and cannot be undone.
And it would be folly to continue making the obsolete product in a misguided attempt to
“recover” the original cost of the machine. In short, the $50,000 originally paid for the
machine is a sunk cost that should be ignored in current decisions.
THE ECONOMICS OF DRIVING YOUR DREAM CAR
IN BUSINESS
The costs of buying, insuring, repairing, and garaging ultra-luxury vehicles can be very expensive. For example, the purchase price alone for a new Lamborghini or Bentley can easily exceed
$300,000. Thus, Gotham Dream Cars offers an alternative to customers who want to drive ultraluxury cars while avoiding the exorbitant costs of ownership. It sells fractional shares in luxury
cars—the minimum price starts at $9,000 for 20 driving-days. George Johnson is a Gotham Dream
Cars customer who spent $30,000 for 90 driving-days in two types of ultra-luxury vehicles. He
noted that “it’s not worth it to buy one of these cars when you have to fix them.” In essence, Johnson compared the costs of ownership with the rental costs and decided to rent.

Summary
In this chapter, we have discussed ways in which managers classify costs. How the costs will be
used—for assigning costs to cost objects, preparing external reports, predicting cost behavior, or
decision making—will dictate how the costs are classified.
For purposes of assigning costs to cost objects such as products or departments, costs are classified as direct or indirect. Direct costs can be conveniently traced to cost objects. Indirect costs
cannot be conveniently traced to cost objects.
For external reporting purposes, costs are classified as either product costs or period costs.
Product costs are assigned to inventories and are considered assets until the products are sold. At the
point of sale, product costs become cost of goods sold on the income statement. In contrast, period
costs are taken directly to the income statement as expenses in the period in which they are incurred.
For purposes of predicting how costs will react to changes in activity, costs are classified into
three categories—variable, fixed, and mixed. Variable costs, in total, are strictly proportional to
activity. The variable cost per unit is constant. Fixed costs, in total, remain the same as the activity
level changes within the relevant range. The average fixed cost per unit decreases as the activity
level increases. Mixed costs consist of variable and fixed elements and can be expressed in equation form as Y 5 a 1 bX, where X is the activity, Y is the total cost, a is the fixed cost element, and
b is the variable cost per unit of activity.
If the relation between cost and activity appears to be linear based on a scattergraph plot, then
the variable and fixed components of a mixed cost can be estimated using the high-low method,
which implicitly draws a straight line through the points of lowest activity and highest activity, or
the least-squares regression method, which uses all of the data points to compute a regression line
that minimizes the sum of the squares errors.
The traditional income statement format is used primarily for external reporting purposes. It
organizes costs using product and period cost classifications. The contribution format income statement aids decision making because it organizes costs using variable and fixed cost classifications.
For purposes of making decisions, the concepts of differential cost and revenue, opportunity
cost, and sunk cost are vitally important. Differential costs and revenues are the costs and revenues
that differ between alternatives. Opportunity cost is the benefit that is forgone when one alternative
is selected over another. Sunk cost is a cost that occurred in the past and cannot be altered. Differential costs and opportunity costs should be carefully considered in decisions. Sunk costs are
always irrelevant in decisions and should be ignored.

Chapter 2
Review Problem 1: Cost Terms
Many new cost terms have been introduced in this chapter. It will take you some time to learn
what each term means and how to properly classify costs in an organization. Consider the following example: Porter Company manufactures furniture, including tables. Selected costs are
given below:
1. The tables are made of wood that costs $100 per table.
2. The tables are assembled by workers, at a wage cost of $40 per table.
3. Workers assembling the tables are supervised by a factory supervisor who is paid $38,000
per year.
4. Electrical costs are $2 per machine-hour. Four machine-hours are required to produce a table.
5. The depreciation on the machines used to make the tables totals $10,000 per year. The
machines have no resale value and do not wear out through use.
6. The salary of the president of the company is $100,000 per year.
7. The company spends $250,000 per year to advertise its products.
8. Salespersons are paid a commission of $30 for each table sold.
9. Instead of producing the tables, the company could rent its factory space for $50,000 per year.
Required:
Classify these costs according to the various cost terms used in the chapter. Carefully study the
classification of each cost. If you don’t understand why a particular cost is classified the way it is,
reread the section of the chapter discussing the particular cost term. The terms variable cost and
fixed cost refer to how costs behave with respect to the number of tables produced in a year.

This is an opportunity cost because it represents the potential benefit that is lost or sacrificed as a result of using the factory space to produce tables. Opportunity cost is a
special category of cost that is not ordinarily recorded in an organization’s accounting records. To avoid possible confusion with other costs, we will not attempt to classify this
cost in any other way except as an opportunity cost.

Use the high-low method to estimate the fixed and variable components of admitting costs.
Express the fixed and variable components of admitting costs as a cost formula in the form
Y 5 a 1 bX.
Solution to Review Problem 2
1.
The first step in the high-low method is to identify the periods of the lowest and highest activity. Those periods are November (1,100 patients admitted) and June (1,900 patients admitted).
The second step is to compute the variable cost per unit using those two data points:
Number of
Patients Admitted

Low activity level (November) . . . . . . . .

Variable cost 5 _______________ 5 __________________ 5 $3 per patient admitted
Change in activity 800 patients admitted
The third step is to compute the fixed cost element by deducting the variable cost element
from the total cost at either the high or low activity. In the computation below, the high point
of activity is used:
Fixed cost element 5 Total cost 2 Variable cost element
5 $15,200 2 ($3 per patient admitted 3 1,900 patients admitted)
5 $9,500

Account analysis A method for analyzing cost behavior in which an account is classified as
either variable or fixed based on the analyst’s prior knowledge of how the cost in the account
behaves. (p. 39)
Activity base A measure of whatever causes the incurrence of a variable cost. For example, the total
cost of X-ray film in a hospital will increase as the number of X-rays taken increases. Therefore,
the number of X-rays is the activity base that explains the total cost of X-ray film. (p. 33)

Administrative costs All executive, organizational, and clerical costs associated with the general
management of an organization rather than with manufacturing or selling. (p. 30)
Committed fixed costs Investments in facilities, equipment, and basic organizational structure
that can’t be significantly reduced even for short periods of time without making fundamental
changes. (p. 35)
Common cost A cost that is incurred to support a number of cost objects but that cannot be traced
to them individually. For example, the wage cost of the pilot of a 747 airliner is a common
cost of all of the passengers on the aircraft. Without the pilot, there would be no flight and no
passengers. But no part of the pilot’s wage is caused by any one passenger taking the flight.

EXERCISE 2–7 Differential, Opportunity, and Sunk Costs [LO2–7]
Northwest Hospital is a full-service hospital that provides everything from major surgery and
emergency room care to outpatient clinics. The hospital’s Radiology Department is considering replacing an old inefficient X-ray machine with a state-of-the-art digital X-ray machine. The
new machine would provide higher quality X-rays in less time and at a lower cost per X-ray. It
would also require less power and would use a color laser printer to produce easily readable X-ray
images. Instead of investing the funds in the new X-ray machine, the Laboratory Department is
lobbying the hospital’s management to buy a new DNA analyzer.
Required:
For each of the items below, indicate by placing an X in the appropriate column whether it should
be considered a differential cost, an opportunity cost, or a sunk cost in the decision to replace the
old X-ray machine with a new machine. If none of the categories apply for a particular item, leave

EXERCISE 2–12 Cost Classification [LO2–2, LO2–3, LO2–4, LO2–7]
Wollogong Group Ltd. of New South Wales, Australia, acquired its factory building about 10 years
ago. For several years, the company has rented out a small annex attached to the rear of the building. The company has received a rental income of $30,000 per year on this space. The renter’s
lease will expire soon, and rather than renewing the lease, the company has decided to use the
space itself to manufacture a new product.
Direct materials cost for the new product will total $80 per unit. To have a place to store
finished units of product, the company will rent a small warehouse nearby. The rental cost will
be $500 per month. In addition, the company must rent equipment for use in producing the new
product; the rental cost will be $4,000 per month. Workers will be hired to manufacture the new
product, with direct labor cost amounting to $60 per unit. The space in the annex will continue to
be depreciated on a straight-line basis, as in prior years. This depreciation is $8,000 per year.
Advertising costs for the new product will total $50,000 per year. A supervisor will be hired to
oversee production; her salary will be $1,500 per month. Electricity for operating machines will be
$1.20 per unit. Costs of shipping the new product to customers will be $9 per unit.

PROBLEM 2–22 High-Low and Scattergraph Analysis [LO2–4, LO2–5]
Pleasant View Hospital of British Columbia has just hired a new chief administrator who is anxious to employ sound management and planning techniques in the business affairs of the hospital.
Accordingly, she has directed her assistant to summarize the cost structure of the various departments so that data will be available for planning purposes.
The assistant is unsure how to classify the utilities costs in the Radiology Department
because these costs do not exhibit either strictly variable or fixed cost behavior. Utilities costs are
very high in the department due to a CAT scanner that draws a large amount of power and is kept
running at all times. The scanner can’t be turned off due to the long warm-up period required for
its use. When the scanner is used to scan a patient, it consumes an additional burst of power. The
assistant has accumulated the following data on utilities costs and use of the scanner since the
first of the year.

The chief administrator has informed her assistant that the utilities cost is probably a mixed
cost that will have to be broken down into its variable and fixed cost elements by use of a scattergraph. The assistant feels, however, that if an analysis of this type is necessary, then the high-low
method should be used, since it is easier and quicker. The controller has suggested that there may
be a better approach.
Required:

3.
Using the high-low method, estimate a cost formula for utilities. Express the formula in the
form Y 5 a 1 bX. (The variable rate should be stated in terms of cost per scan.)
Prepare a scattergraph by plotting the number of scans and utility cost on a graph. Draw a
straight line though the two data points that correspond to the high and low levels of activity.
Make sure your line intersects the Y-axis.
Comment on the accuracy of your high-low estimates assuming a least-squares regression
analysis estimated the total fixed costs to be $1,170.90 per month and the variable cost to be
$18.18 per scan. How would the straight line that you drew in requirement 2 differ from a
straight line that minimizes the sum of the squared errors?

PROBLEM 2–24 Ethics and the Manager [LO2–3]
M. K. Gallant is president of Kranbrack Corporation, a company whose stock is traded on a national
exchange. In a meeting with investment analysts at the beginning of the year, Gallant had predicted
that the company’s earnings would grow by 20% this year. Unfortunately, sales have been less than
expected for the year, and Gallant concluded within two weeks of the end of the fiscal year that it
would be impossible to ultimately report an increase in earnings as large as predicted unless some
drastic action was taken. Accordingly, Gallant has ordered that wherever possible, expenditures
should be postponed to the new year—including canceling or postponing orders with suppliers,
delaying planned maintenance and training, and cutting back on end-of-year advertising and travel.
Additionally, Gallant ordered the company’s controller to carefully scrutinize all costs that are currently classified as period costs and reclassify as many as possible as product costs. The company
is expected to have substantial inventories at the end of the year.
Required:

Appendix 2A: Least-Squares Regression Computations
The least-squares regression method for estimating a linear relationship is based on the
equation for a straight line:
Y 5 a 1 bX
As explained in the chapter, least-squares regression selects the values for the intercept
a and the slope b that minimize the sum of the squared errors. The following formulas,
which are derived in statistics and calculus texts, accomplish that objective:
n(SXY ) 2 (SX )(SY )
b 5 __________________
n(SX2) 2 (SX )2
(SY ) 2 b(SX )
a 5 ____________
n
where:
X 5 The level of activity (independent variable)
Y 5 The total mixed cost (dependent variable)
a 5 The total fixed cost (the vertical intercept of the line)
b 5 The variable cost per unit of activity (the slope of the line)
n 5 Number of observations
S 5 Sum across all n observations
Manually performing the calculations required by the formulas is tedious at best.
Fortunately, Microsoft® Excel can be used to estimate the intercept (fixed cost) and
slope (variable cost per unit) that minimize the sum of the squared errors. Excel also
provides a statistic called the R2, which is a measure of “goodness of fit.” The R2 tells
us the percentage of the variation in the dependent variable (cost) that is explained by
variation in the independent variable (activity). The R2 varies from 0% to 100%, and the
higher the percentage, the better. You should always plot the data in a scattergraph, but
it is particularly important to check the data visually when the R2 is low. A quick look at
the scattergraph can reveal that there is little relation between the cost and the activity or
that the relation is something other than a simple straight line. In such cases, additional
analysis would be required.
To illustrate how Excel can be used to prepare a scattergraph plot and to calculate the
intercept a, the slope b, and the R2, we will use the Brentline Hospital data for patientdays and maintenance costs on page 39 (which is recreated in Exhibit 2A–1).1
To prepare a scattergraph plot, begin by highlighting the data in cells B4 through
C10. From the Charts group within the Insert tab, select the “Scatter” subgroup and then
click on the choice that has no lines connecting the data points. This should produce a
scattergraph plot similar to the one shown in Exhibit 2A–2. Notice that the number of
patient-days is plotted on the X-axis and the maintenance costs are plotted on the Y-axis.2
The data is approximately linear, so it makes sense to proceed with estimating a regression equation that minimizes the sum of the squared errors.

EXHIBIT 2A–1
The Least-Squares Regression
Worksheet for Brentline Hospital
To determine the intercept a, the slope b, and the R2, begin by right clicking on any
data point in the scattergraph plot and selecting “Add Trendline.” This should produce
the screen that is shown in Exhibit 2A–3. Notice that under “Trend/Regression Type”
you should select “Linear.” Similarly, under “Trendline Name” you should select “Automatic.” Next to the word “Backward” you should input the lowest value for the independent variable, which in this example is 5000 patient-days. Taking this particular step
instructs Excel to extend your fitted line until it intersects the Y-axis. Finally, you should
check the two boxes at the bottom of Exhibit 2A–3 that say “Display Equation on chart”
and “Display R-squared value on chart.”
Once you have established these settings, then click “Close.” As shown in Exhibit 2A–4,
this will automatically insert a line within the scattergraph plot that minimizes the sum
of the squared errors. It will also cause the estimated least-squares regression equation and R2 to be inserted into your scattergraph plot. Instead of depicting the results
using the form Y 5 a 1 bX, Excel uses an equivalent form of the equation depicted
as Y 5 bX 1 a. In other words, Excel reverses the two terms shown to the right of the
equals sign. So, in Exhibit 2A–4, Excel shows a least-squares regression equation of
y 5 0.7589x 1 3,430.9. The slope b in this equation of $0.7589 represents the estimated
variable maintenance cost per patient-day. The intercept a in this equation of $3,430.90
(or approximately $3,431) represents the estimated fixed monthly maintenance cost.
Note that the R2 is approximately 0.90, which is quite good and indicates that 90% of the
variation in maintenance costs is explained by the variation in patient-days.

PROBLEM 2A–3 Least-Squares Regression; Scattergraph; Comparison of Activity Bases [LO2–4, LO2–8]
The Hard Rock Mining Company is developing cost formulas for management planning and
decision-making purposes. The company’s cost analyst has concluded that utilities cost is a mixed
cost, and he is attempting to find a base with which the cost might be closely correlated. The controller has suggested that tons mined might be a good base to use in developing a cost formula. The

functions. Chavez’s business is seasonal, with a heavy schedule during the summer months and
holidays and a lighter schedule at other times.

Chapter 2
One of the major events Chavez’s customers request is a cocktail party. She offers a standard
cocktail party and has estimated the cost per guest as follows:
Food and beverages . . . . . . . . . . . . . . .
Labor (0.5 hrs. @ $10.00/hr.) . . . . . . . . .
Overhead (0.5 hrs. @ $13.98/hr.) . . . . . .

6.99
Total cost per guest . . . . . . . . . . . . . . . .
$26.99
The standard cocktail party lasts three hours and Chavez hires one worker for every six guests,
so that works out to one-half hour of labor per guest. These workers are hired only as needed and
are paid only for the hours they actually work.
When bidding on cocktail parties, Chavez adds a 15% markup to yield a price of about
$31 per guest. She is confident about her estimates of the costs of food and beverages and
labor but is not as comfortable with the estimate of overhead cost. The $13.98 overhead cost
per labor-hour was determined by dividing total overhead expenses for the last 12 months
by total labor-hours for the same period. Monthly data concerning overhead costs and laborhours follow:

Appendix 2B: Cost of Quality
A company may have a product with a high-quality design that uses high-quality components, but if the product is poorly assembled or has other defects, the company will
have high warranty repair costs and dissatisfied customers. People who are dissatisfied
with a product are unlikely to buy the product again. They often tell others about their
bad experiences. This is the worst possible sort of advertising. To prevent such problems,
companies expend a great deal of effort to reduce defects. The objective is to have high
quality of conformance.
Quality of Conformance
A product that meets or exceeds its design specifications and is free of defects that mar its
appearance or degrade its performance is said to have high quality of conformance. Note
that if an economy car is free of defects, it can have a quality of conformance that is just as
high as a defect-free luxury car. The purchasers of economy cars cannot expect their cars to
be as opulently equipped as luxury cars, but they can and do expect them to be free of defects.
Preventing, detecting, and dealing with defects causes costs that are called quality
costs or the cost of quality. The use of the term quality cost is confusing to some people. It
does not refer to costs such as using a higher-grade leather to make a wallet or using 14K
gold instead of gold-plating in jewelry. Instead, the term quality cost refers to all of the
costs that are incurred to prevent defects or that result from defects in products.
Quality costs can be broken down into four broad groups. Two of these groups—
known as prevention costs and appraisal costs—are incurred in an effort to keep defective
products from falling into the hands of customers. The other two groups of costs—known
as internal failure costs and external failure costs—are incurred because defects occur
despite efforts to prevent them. Examples of specific costs involved in each of these four
groups are given in Exhibit 2B–1.
Several things should be noted about the quality costs shown in the exhibit. First,
quality costs don’t relate to just manufacturing; rather, they relate to all the activities in
a company from initial research and development (R&D) through customer service. Second, the number of costs associated with quality is very large; total quality cost can be
very high unless management gives this area special attention. Finally, the costs in the four
groupings are quite different. We will now look at each of these groupings more closely.
Prevention Costs
Generally, the most effective way to manage quality costs is to avoid having defects in
the first place. It is much less costly to prevent a problem from ever happening than it is
to find and correct the problem after it has occurred. Prevention costs support activities
whose purpose is to reduce the number of defects.
Note from Exhibit 2B–1 that prevention costs include activities relating to quality
circles and statistical process control. Quality circles consist of small groups of employees that meet on a regular basis to discuss ways to improve quality. Both management and
workers are included in these circles. Quality circles are widely used and can be found
in manufacturing companies, utilities, health care organizations, banks, and many other
organizations.
Statistical process control is a technique that is used to detect whether a process
is in or out of control. An out-of-control process results in defective units and may be
caused by a miscalibrated machine or some other factor. In statistical process control,
workers use charts to monitor the quality of units that pass through their workstations.
With these charts, workers can quickly spot processes that are out of control and that are
creating defects. Problems can be immediately corrected and further defects prevented
rather than waiting for an inspector to catch the defects later.
Note also from the list of prevention costs in Exhibit 2B–1 that some companies
provide technical support to their suppliers as a way of preventing defects. Particularly

costs and explain how they

in just-in-time (JIT) systems, such support to suppliers is vital. In a JIT system, parts
are delivered from suppliers just in time and in just the correct quantity to fill customer
orders. There are no parts stockpiles. If a defective part is received from a supplier, the
part cannot be used and the order for the ultimate customer cannot be filled on time.
Hence, every part received from a supplier must be free of defects. Consequently, companies that use JIT often require that their suppliers use sophisticated quality control
programs such as statistical process control and that their suppliers certify that they will
deliver parts and materials that are free of defects.
Appraisal Costs
Any defective parts and products should be caught as early as possible in the production
process. Appraisal costs, which are sometimes called inspection costs, are incurred to
identify defective products before the products are shipped to customers. Unfortunately,
performing appraisal activities doesn’t keep defects from happening again, and most
managers now realize that maintaining an army of inspectors is a costly (and ineffective)
approach to quality control. Therefore, employees are increasingly being asked to be
responsible for their own quality control. This approach, along with designing products
to be easy to manufacture properly, allows quality to be built into products rather than
relying on inspection to get the defects out.
Internal Failure Costs
Failure costs are incurred when a product fails to conform to its design specifications.
Failure costs can be either internal or external. Internal failure costs result from identifying defects before they are shipped to customers. These costs include scrap, rejected
Managerial Accounting and Cost Concepts
75
products, reworking of defective units, and downtime caused by quality problems. In
some companies, as little as 10% of the company’s products make it through the production process without rework of some kind. Of course, the more effective a company’s
appraisal activities, the greater the chance of catching defects internally and the greater
the level of internal failure costs. This is the price that is paid to avoid incurring external
failure costs, which can be devastating.
External Failure Costs
External failure costs result when a defective product is delivered to a customer. As
shown in Exhibit 2B–1, external failure costs include warranty repairs and replacements,
product recalls, liability arising from legal action against a company, and lost sales arising from a reputation for poor quality. Such costs can decimate profits.
In the past, some managers have taken the attitude, “Let’s go ahead and ship everything to customers, and we’ll take care of any problems under the warranty.” This attitude
generally results in high external failure costs, customer ill will, and declining market
share and profits.
Distribution of Quality Costs
Quality costs for some companies range between 10% and 20% of total sales, whereas
experts say that these costs should be more in the 2% to 4% range. How does a company
reduce its total quality cost? The answer lies in how the quality costs are distributed.
Refer to the graph in Exhibit 2B–2, which shows total quality costs as a function of the
quality of conformance.
The graph shows that when the quality of conformance is low, total quality cost is
high and that most of this cost consists of costs of internal and external failure. A low
quality of conformance means that a high percentage of units are defective and hence
the company has high failure costs. However, as a company spends more and more on
prevention and appraisal, the percentage of defective units drops. This results in lower
internal and external failure costs. Ordinarily, total quality cost drops rapidly as the quality of conformance increases. Thus, a company can reduce its total quality cost by focusing its efforts on prevention and appraisal. The cost savings from reduced defects usually
swamp the costs of the additional prevention and appraisal efforts.

Chapter 2
The graph in Exhibit 2B–2 has been drawn so that the total quality cost is minimized
when the quality of conformance is less than 100%. However, some experts contend that
the total quality cost is not minimized until the quality of conformance is 100% and there
are no defects. Indeed, many companies have found that the total quality costs seem to
keep dropping even when the quality of conformance approaches 100% and defect rates
get as low as 1 in a million units. Others argue that total quality cost eventually increases
as the quality of conformance increases. However, in most companies this does not seem
to happen until the quality of conformance is very close to 100% and defect rates are very
close to zero.
As a company’s quality program becomes more refined and as its failure costs begin
to fall, prevention activities usually become more effective than appraisal activities.
Appraisal can only find defects, whereas prevention can eliminate them. The best way
to prevent defects from happening is to design processes that reduce the likelihood of
defects and to continually monitor processes using statistical process control methods.
Quality Cost Reports
LO2–10
Prepare and interpret a quality
cost report.
As an initial step in quality improvement programs, companies often construct a quality
cost report that provides an estimate of the financial consequences of the company’s current level of defects. A quality cost report details the prevention costs, appraisal costs,
and costs of internal and external failures that arise from the company’s current quality
control efforts. Managers are often shocked by the magnitude of these costs. A typical
quality cost report is shown in Exhibit 2B–3.
Several things should be noted from the data in the exhibit. First, Ventura Company’s
quality costs are poorly distributed in both years, with most of the costs due to either
internal failure or external failure. The external failure costs are particularly high in Year
1 in comparison to other costs.
Second, note that the company increased its spending on prevention and appraisal
activities in Year 2. As a result, internal failure costs went up in that year (from $2 million in Year 1 to $3 million in Year 2), but external failure costs dropped sharply (from
$5.15 million in Year 1 to only $2 million in Year 2). Because of the increase in appraisal
activity in Year 2, more defects were caught inside the company before they were shipped
to customers. This resulted in more cost for scrap, rework, and so forth, but saved huge
amounts in warranty repairs, warranty replacements, and other external failure costs.
Third, note that as a result of greater emphasis on prevention and appraisal, total quality cost decreased in Year 2. As continued emphasis is placed on prevention and appraisal
in future years, total quality cost should continue to decrease. That is, future increases in
prevention and appraisal costs should be more than offset by decreases in failure costs.
Moreover, appraisal costs should also decrease as more effort is placed into prevention.
Quality Cost Reports in Graphic Form
As a supplement to the quality cost report shown in Exhibit 2B–3, companies frequently
prepare quality cost information in graphic form. Graphic presentations include pie charts,
bar graphs, trend lines, and so forth. The data for Ventura Company from Exhibit 2B–3
are presented in bar graph form in Exhibit 2B–4.
The first bar graph in Exhibit 2B–4 is scaled in terms of dollars of quality cost, and
the second is scaled in terms of quality cost as a percentage of sales. In both graphs, the
data are “stacked” upward. That is, appraisal costs are stacked on top of prevention costs,
internal failure costs are stacked on top of the sum of prevention costs plus appraisal
costs, and so forth. The percentage figures in the second graph show that total quality cost
equals 18% of sales in Year 1 and 15% of sales in Year 2, the same as reported earlier in
Exhibit 2B–3.

computer graphics and spreadsheet applications.
Uses of Quality Cost Information
A quality cost report has several uses. First, quality cost information helps managers see
the financial significance of defects. Managers usually are not aware of the magnitude of
their quality costs because these costs cut across departmental lines and are not normally
tracked and accumulated by the cost system. Thus, when first presented with a quality cost
report, managers often are surprised by the amount of cost attributable to poor quality.
Second, quality cost information helps managers identify the relative importance of
the quality problems faced by their companies. For example, the quality cost report may
show that scrap is a major quality problem or that the company is incurring huge warranty
costs. With this information, managers have a better idea of where to focus their efforts.
Third, quality cost information helps managers see whether their quality costs are
poorly distributed. In general, quality costs should be distributed more toward prevention
and appraisal activities and less toward failures.

Counterbalancing these uses, three limitations of quality cost information should
be recognized. First, simply measuring and reporting quality costs does not solve quality problems. Problems can be solved only by taking action. Second, results usually lag
behind quality improvement programs. Initially, total quality cost may even increase as
quality control systems are designed and installed. Decreases in quality costs may not
begin to occur until the quality program has been in effect for some time. And third, the
most important quality cost, lost sales arising from customer ill will, is usually omitted
from the quality cost report because it is difficult to estimate.
Typically, during the initial years of a quality improvement program, the benefits
of compiling a quality cost report outweigh the costs and limitations of the reports. As
managers gain experience in balancing prevention and appraisal activities, the need for
quality cost reports often diminishes.
International Aspects of Quality
Many of the tools used in quality management today were developed in Japan after World
War II. In statistical process control, Japanese companies borrowed heavily from the
work of W. Edwards Deming. However, Japanese companies are largely responsible for
quality circles, JIT, the idea that quality is everyone’s responsibility, and the emphasis on
prevention rather than on inspection.
In the 1980s, quality reemerged as a pivotal factor in the market. Many companies now
find that it is impossible to effectively compete without a very strong quality program in
place. This is particularly true of companies that wish to compete in the European market.
The ISO 9000 Standards
The International Organization for Standardization (ISO), based in Geneva, Switzerland,
has established quality control guidelines known as the ISO 9000 standards. Many companies and organizations in Europe will buy only from ISO 9000-certified suppliers. This
means that the suppliers must demonstrate to a certifying agency that:
Managerial Accounting and Cost Concepts
1. A quality control system is in use, and the system clearly defines an expected level of
quality.
2. The system is fully operational and is backed up with detailed documentation of
quality control procedures.
3. The intended level of quality is being achieved on a sustained, consistent basis.
The key to receiving certification under the ISO 9000 standards is documentation. It’s
one thing for a company to say that it has a quality control system in operation, but it’s
quite a different thing to be able to document the steps in that system. Under ISO 9000,
this documentation must be so detailed and precise that if all the employees in a company were suddenly replaced, the new employees could use the documentation to make
the product exactly as it was made by the old employees. Even companies with good
quality control systems find that it takes up to two years of painstaking work to develop
this detailed documentation. But companies often find that compiling this documentation
results in improvements in their quality systems.
The ISO 9000 standards have become an international measure of quality. Although
the standards were developed to control the quality of goods sold in European countries, they have become widely accepted elsewhere as well. Companies in the United
States that export to Europe often expect their own suppliers to comply with ISO 9000
standards because these exporters must document the quality of the materials going into
their products as part of their own ISO 9000 certification.
The ISO program for certification of quality management programs is not limited to
manufacturing companies. The American Institute of Certified Public Accountants was
the first professional membership organization in the United States to win recognition
under an ISO certification program.
Summary (Appendix 2B)
Defects cause costs, which can be classified into prevention costs, appraisal costs, internal failure
costs, and external failure costs. Prevention costs are incurred to keep defects from happening.
Appraisal costs are incurred to ensure that defective products, once made, are not shipped to customers. Internal failure costs are incurred as a consequence of detecting defective products before
they are shipped to customers. External failure costs are the consequences (in terms of repairs, servicing, and lost future business) of delivering defective products to customers. Most experts agree
that management effort should be focused on preventing defects. Small investments in prevention
can lead to dramatic reductions in appraisal costs and costs of internal and external failure.
Quality costs are summarized on a quality cost report. This report shows the types of quality
costs being incurred and their significance and trends. The report helps managers understand the
importance of quality costs, spot problem areas, and assess the way in which the quality costs are
distributed.

PROBLEM 2B–3 Analyzing a Quality Cost Report [LO2–10]
Mercury, Inc., produces cell phones at its plant in Texas. In recent years, the company’s market
share has been eroded by stiff competition from overseas. Price and product quality are the two key
areas in which companies compete in this market.
A year ago, the company’s cell phones had been ranked low in product quality in a consumer survey. Shocked by this result, Jorge Gomez, Mercury’s president, initiated a crash effort
to improve product quality. Gomez set up a task force to implement a formal quality improvement
program. Included on this task force were representatives from the Engineering, Marketing, Customer Service, Production, and Accounting departments. The broad representation was needed
because Gomez believed that this was a companywide program and that all employees should
share the responsibility for its success.
After the first meeting of the task force, Holly Elsoe, manager of the Marketing Department,
asked John Tran, production manager, what he thought of the proposed program. Tran replied,
“I have reservations. Quality is too abstract to be attaching costs to it and then to be holding you
and me responsible for cost improvements. I like to work with goals that I can see and count! I’m
nervous about having my annual bonus based on a decrease in quality costs; there are too many
variables that we have no control over.”
Mercury’s quality improvement program has now been in operation for one year. The company’s most recent quality cost report is shown below.

As they were reviewing the report, Elsoe asked Tran what he now thought of the quality
improvement program. Tran replied. “I’m relieved that the new quality improvement program
hasn’t hurt our bonuses, but the program has increased the workload in the Production Department.
It is true that customer returns are way down, but the cell phones that were returned by customers
to retail outlets were rarely sent back to us for rework.”

University Tees was founded in 2003 by two Miami University college
students to provide screen-printing, embroidery, and promotional products
for fraternities, sororities, and student organizations. Today, the company,
which is headquartered in Cleveland, Ohio, employs as many as four Campus
Managers on each of over 150 college campuses across America.
Accurately calculating the cost of each potential customer order is
critically important to University Tees because the company needs to be
sure that the sales price exceeds the cost associated with satisfying the
order. The costs include the cost of the blank T-shirts themselves, printing costs (which vary depending on the quantity of shirts produced and the
number of colors per shirt), screen costs (which also vary depending on
the number of colors included in a design), shipping costs, and the artwork
needed to create a design. The company also takes into account its competitors’ pricing strategies when developing its own prices.
Given its success on college campuses, University Tees has introduced a
sister company called On Point Promos to serve for-profit companies and
nonprofit organizations. ■

Chapter 3
nderstanding how products and services are costed is vital to
U
managers because the way in which these costs are determined can have a substantial impact on reported profits, as well as on key management decisions.
A managerial costing system should provide cost data to help managers plan, control, and make decisions. Nevertheless, external financial reporting and
tax reporting requirements often heavily influence how costs are accumulated and summarized on managerial reports. This is true of product costing. In this chapter we use
absorption costing to determine product costs. In absorption costing, all manufacturing
costs, both fixed and variable, are assigned to units of product—units are said to fully
absorb manufacturing costs.
Most countries—including the United States—require some form of absorption
costing for both external financial reports and for tax reports. In addition, the vast
majority of companies throughout the world also use absorption costing in their management reports. Because absorption costing is the most common approach to product
costing throughout the world, we discuss it first and then discuss the alternatives in
subsequent chapters.
Job-Order Costing—An Overview
Under absorption costing, product costs include all manufacturing costs. Some manufacturing costs, such as direct materials, can be directly traced to particular products.
For example, the cost of the airbags installed in a Toyota Camry can be easily traced
to that particular auto. But what about manufacturing costs like factory rent? Such
costs do not change from month to month, whereas the number and variety of products
made in the factory may vary dramatically from one month to the next. Because these
costs remain unchanged from month to month regardless of what products are made,
they are clearly not caused by—and cannot be directly traced to—any particular product. Therefore, these types of costs are assigned to products and services by averaging
across time and across products. The type of production process influences how this
averaging is done.
Job-order costing is used in situations where many different products, each
with individual and unique features, are produced each period. For example, a Levi
Strauss clothing factory would typically make many different types of jeans for both
men and women during a month. A particular order might consist of 1,000 boot-cut
men’s blue denim jeans, style number A312. This order of 1,000 jeans is called a
job. In a job-order costing system, costs are traced and allocated to jobs and then the
costs of the job are divided by the number of units in the job to arrive at an average
cost per unit.
Other examples of situations where job-order costing would be used include
large-scale construction projects managed by Bechtel International, commercial aircraft produced by Boeing, greeting cards designed and printed by Hallmark, and
airline meals prepared by LSG SkyChefs. All of these examples are characterized by
diverse outputs. Each Bechtel project is unique and different from every other—the
company may be simultaneously constructing a dam in Nigeria and a bridge in Indonesia. Likewise, each airline orders a different type of meal from LSG SkyChefs’
catering service.
Job-order costing is also used extensively in service industries. For example, hospitals, law firms, movie studios, accounting firms, advertising agencies, and repair
shops all use a variation of job-order costing to accumulate costs. Although the detailed
example of job-order costing provided in the following section deals with a manufacturing company, the same basic concepts and procedures are used by many service
organizations.

IS THIS REALLY A JOB?
VBT Bicycling Vacations of Bristol, Vermont, offers deluxe bicycling vacations in the United States,
Canada, Europe, and other locations throughout the world. For example, the company offers a
10-day tour of the Puglia region of Italy—the “heel of the boot.” The tour price includes international
airfare, 10 nights of lodging, most meals, use of a bicycle, and ground transportation as needed.
Each tour is led by at least two local tour leaders, one of whom rides with the guests along the
tour route. The other tour leader drives a “sag wagon” that carries extra water, snacks, and bicycle
repair equipment and is available for a shuttle back to the hotel or up a hill. The sag wagon also
transports guests’ luggage from one hotel to another.
Each specific tour can be considered a job. For example, Giuliano Astore and Debora Trippetti,
two natives of Puglia, led a VBT tour with 17 guests over 10 days in late April. At the end of the tour,
Giuliano submitted a report, a sort of job cost sheet, to VBT headquarters. This report detailed the
on the ground expenses incurred for this specific tour, including fuel and operating costs for the van,
lodging costs for the guests, the costs of meals provided to guests, the costs of snacks, the cost of
hiring additional ground transportation as needed, and the wages of the tour leaders. In addition to
these costs, some costs are paid directly by VBT in Vermont to vendors. The total cost incurred for
the tour is then compared to the total revenue collected from guests to determine the gross profit
for the tour.

Job-Order Costing—An Example
To introduce job-order costing, we will follow a specific job as it progresses through the
manufacturing process. This job consists of two experimental couplings that Yost Precision Machining has agreed to produce for Loops Unlimited, a manufacturer of roller
coasters. Couplings connect the cars on the roller coaster and are a critical component in
the performance and safety of the ride. Before we begin our discussion, recall from the
previous chapter that companies generally classify manufacturing costs into three broad
categories: (1) direct materials, (2) direct labor, and (3) manufacturing overhead. As we
study the operation of a job-order costing system, we will see how each of these three
types of costs is recorded and accumulated.
Yost Precision Machining is a small company in Michigan that specializes in fabricating precision metal parts that are used in a variety of applications ranging from deepsea exploration vehicles to the inertial triggers in automobile air bags. The company’s
top managers gather every morning at 8:00 a.m. in the company’s conference room for
the daily planning meeting. Attending the meeting this morning are: Jean Yost, the company’s president; David Cheung, the marketing manager; Debbie Turner, the production
manager; and Marc White, the company controller. The president opened the meeting:
Jean: The production schedule indicates we’ll be starting Job 2B47 today. Isn’t that the
special order for experimental couplings, David?
David: That’s right. That’s the order from Loops Unlimited for two couplings for their
new roller coaster ride for Magic Mountain.
Debbie: Why only two couplings? Don’t they need a coupling for every car?
David: Yes. But this is a completely new roller coaster. The cars will go faster and will
be subjected to more twists, turns, drops, and loops than on any other existing roller
coaster. To hold up under these stresses, Loops Unlimited’s engineers completely
redesigned the cars and couplings. They want us to make just two of these new couplings for testing purposes. If the design works, then we’ll have the inside track on
the order to supply couplings for the whole ride.

Jean: We agreed to take on this initial order at our cost just to get our foot in the door.
Marc, will there be any problem documenting our cost so we can get paid?
Marc: No problem. The contract with Loops stipulates that they will pay us an amount
equal to our cost of goods sold. With our job-order costing system, I can tell you the
cost on the day the job is completed.
Jean: Good. Is there anything else we should discuss about this job at this time? No?
Well then let’s move on to the next item of business.
Measuring Direct Materials Cost
The blueprints submitted by Loops Unlimited indicate that each experimental coupling
will require three parts that are classified as direct materials: two G7 Connectors and one
M46 Housing. Since each coupling requires two connectors and one housing, the production of two couplings requires four connectors and two housings. This is a custom product that is being made for the first time, but if this were one of the company’s standard
products, it would have an established bill of materials. A bill of materials is a document
that lists the type and quantity of each type of direct material needed to complete a unit
of product.
When an agreement has been reached with the customer concerning the quantities,
prices, and shipment date for the order, a production order is issued. The Production
Department then prepares a materials requisition form similar to the form in Exhibit 3–1.
The materials requisition form is a document that specifies the type and quantity of
materials to be drawn from the storeroom and identifies the job that will be charged for
the cost of the materials. The form is used to control the flow of materials into production
and also for making entries in the accounting records.
The Yost Precision Machining materials requisition form in Exhibit 3–1 shows that
the company’s Milling Department has requisitioned two M46 Housings and four G7
Connectors for the Loops Unlimited job, which has been designated as Job 2B47.
Job Cost Sheet
After a production order has been issued, the Accounting Department’s job-order costing software system automatically generates a job cost sheet like the one presented in
Exhibit 3–2. A job cost sheet records the materials, labor, and manufacturing overhead
costs charged to that job.

SUPPLY AND DEMAND INFLUENCE LUMBER PRICES
When the housing market crumbled between 2005 and 2009, lumber mills responded by slashing
output by 45%. However, in 2010 many home builders decided to expand speculative construction on the belief that an expiring federal tax credit would entice more customers to purchase new
homes. The result of plummeting supply coupled with an uptick in demand was predictable—the
price of lumber spiked to $279 per thousand board feet, thereby adding about $1,000 to the price
of a typical new home. Pulte Homes told investors that it would attempt to offset the increase in
direct materials cost by reducing its labor costs.
Home builders use job-order costing systems to accumulate the costs incurred to build each
new home. When materials and labor costs fluctuate, job-order costing systems can measure these
impacts on each customer’s new home construction costs.
Source: Liam Pleven and Lester Aldrich, “Builders Nailed by Lumber Prices,” The Wall Street Journal, February
16, 2010, pp. C1 and C4.
After direct materials are issued, the cost of these materials are automatically
recorded on the job cost sheet. Note from Exhibit 3–2, for example, that the $660 cost for
direct materials shown earlier on the materials requisition form has been charged to Job
2B47 on its job cost sheet. The requisition number 14873 from the materials requisition
form appears on the job cost sheet to make it easier to identify the source document for
the direct materials charge.

Chapter 3
Measuring Direct Labor Cost
Direct labor consists of labor charges that are easily traced to a particular job. Labor
charges that cannot be easily traced directly to any job are treated as part of manufacturing overhead. As discussed in the previous chapter, this latter category of labor costs is
called indirect labor and includes tasks such as maintenance, supervision, and cleanup.
Most companies rely on computerized systems to maintain employee time tickets. A
completed time ticket is an hour-by-hour summary of the employee’s activities throughout the day. One computerized approach to creating time tickets uses bar codes to capture
data. Each employee and each job has a unique bar code. When beginning work on a
job, the employee scans three bar codes using a handheld device much like the bar code
readers at grocery store checkout stands. The first bar code indicates that a job is being
started; the second is the unique bar code on the employee’s identity badge; and the third
is the unique bar code of the job itself. This information is fed automatically via an electronic network to a computer that notes the time and records all of the data. When the
task is completed, the employee scans a bar code indicating the task is complete, the bar
code on his or her identity badge, and the bar code attached to the job. This information
is relayed to the computer that again notes the time, and a time ticket, such as the one
shown in Exhibit 3–3, is automatically prepared. Because all of the source data is already
in computer files, the labor costs can be automatically posted to job cost sheets. For
example, Exhibit 3–3 shows $45 of direct labor cost related to Job 2B47. This amount
is automatically posted to the job cost sheet shown in Exhibit 3–2. The time ticket in
Exhibit 3–3 also shows $9 of indirect labor costs related to performing maintenance.
This cost is treated as part of manufacturing overhead and does not get posted on a job
cost sheet.
LO3–1
Computing Predetermined Overhead Rates
Compute a predetermined
overhead rate.
Recall that product costs include manufacturing overhead as well as direct materials and
direct labor. Therefore, manufacturing overhead also needs to be recorded on the job cost
sheet. However, assigning manufacturing overhead to a specific job involves some difficulties. There are three reasons for this:
1. Manufacturing overhead is an indirect cost. This means that it is either impossible or
difficult to trace these costs to a particular product or job.
2. Manufacturing overhead consists of many different types of costs ranging from the
grease used in machines to the annual salary of the production manager. Some of
these costs are variable overhead costs because they vary in direct proportion to
changes in the level of production (e.g., indirect materials, supplies, and power) and

some are fixed overhead costs because they remain constant as the level of production fluctuates (e.g., heat and light, property taxes, and insurance).
3. Because of the fixed costs in manufacturing overhead, total manufacturing overhead
costs tend to remain relatively constant from one period to the next even though the
number of units produced can fluctuate widely. Consequently, the average cost per
unit will vary from one period to the next.
Given these problems, allocation is used to assign overhead costs to products. Allocation is accomplished by selecting an allocation base that is common to all of the company’s
products and services. An allocation base is a measure such as direct labor-hours (DLH)
or machine-hours (MH) that is used to assign overhead costs to products and services. The
most widely used allocation bases in manufacturing are direct labor-hours, direct labor
cost, machine-hours, and (where a company has only a single product) units of product.
Manufacturing overhead is commonly assigned to products using a predetermined
overhead rate. The predetermined overhead rate is computed by dividing the total estimated manufacturing overhead cost for the period by the estimated total amount of the
allocation base as follows:
Estimated total manufacturing overhead cost
Predetermined overhead rate 5 _______________________________
Estimated total amount of the allocation base
The predetermined overhead rate is computed before the period begins using a four-step
process. The first step is to estimate the total amount of the allocation base (the denominator) that will be required for next period’s estimated level of production. The second
step is to estimate the total fixed manufacturing overhead cost for the coming period and
the variable manufacturing overhead cost per unit of the allocation base. The third step
is to use the cost formula shown below to estimate the total manufacturing overhead cost
(the numerator) for the coming period:
Y 5 a 1 bX
where,
Y 5 The estimated total manufacturing overhead cost
a 5 The estimated total fixed manufacturing overhead cost
b 5 The estimated variable manufacturing overhead cost per unit of the
allocation base
X 5 The estimated total amount of the allocation base
The fourth step is to compute the predetermined overhead rate. Notice, the estimated
amount of the allocation base is determined before estimating the total manufacturing
overhead cost. This needs to be done because total manufacturing overhead cost includes
variable overhead costs that depend on the amount of the allocation base.
Applying Manufacturing Overhead
To repeat, the predetermined overhead rate is computed before the period begins. The
predetermined overhead rate is then used to apply overhead cost to jobs throughout the
period. The process of assigning overhead cost to jobs is called overhead application.
The formula for determining the amount of overhead cost to apply to a particular job is:

For example, if the predetermined overhead rate is $8 per direct labor-hour, then $8 of
overhead cost is applied to a job for each direct labor-hour incurred on the job. When the
allocation base is direct labor-hours, the formula becomes:

Manufacturing Overhead—A Closer Look
To illustrate the steps involved in computing and using a predetermined overhead rate,
let’s return to Yost Precision Machining and make the following assumptions. In step
one, the company estimated that 40,000 direct labor-hours would be required to support
the production planned for the year. In step two, it estimated $220,000 of total fixed
manufacturing overhead cost for the coming year and $2.50 of variable manufacturing
overhead cost per direct labor-hour. Given these assumptions, in step three the company
used the cost formula shown below to estimate its total manufacturing overhead cost for
the year:
Y 5 a 1 bX
Y 5 $220,000 1 ($2.50 per direct labor-hour 3 40,000 direct labor-hours)
Y 5 $220,000 1 $100,000
Y 5 $320,000
In step four, Yost Precision Machining computed its predetermined overhead rate for
the year of $8 per direct labor-hour as shown below:
Estimated total manufacturing overhead cost
Predetermined overhead rate 5 _____________________________________
Estimated total amount of the allocation base
$320,000
5 _____________________
40,000 direct labor-hours
5 $8 per direct labor-hour
The job cost sheet in Exhibit 3–4 indicates that 27 direct labor-hours (i.e., DLHs)
were charged to Job 2B47. Therefore, a total of $216 of manufacturing overhead cost
would be applied to the job:

5 $8 per DLH 3 27 DLHs
5 $216 of overhead applied to Job 2B47
This amount of overhead has been entered on the job cost sheet in Exhibit 3–4. Note that
this is not the actual amount of overhead caused by the job. Actual overhead costs are not
assigned to jobs—if that could be done, the costs would be direct costs, not overhead. The
overhead assigned to the job is simply a share of the total overhead that was estimated at
the beginning of the year. A normal cost system, which we have been describing, applies
overhead to jobs by multiplying a predetermined overhead rate by the actual amount of
the allocation base incurred by the jobs.
The Need for a Predetermined Rate
Instead of using a predetermined rate based on estimates, why not base the overhead rate
on the actual total manufacturing overhead cost and the actual total amount of the allocation base incurred on a monthly, quarterly, or annual basis? If an actual rate is computed
monthly or quarterly, seasonal factors in overhead costs or in the allocation base can
produce fluctuations in the overhead rate. For example, the costs of heating and cooling a factory in Illinois will be highest in the winter and summer months and lowest in
the spring and fall. If the overhead rate is recomputed at the end of each month or each
quarter based on actual costs and activity, the overhead rate would go up in the winter and
summer and down in the spring and fall. As a result, two identical jobs, one completed
in the winter and one completed in the spring, would be assigned different manufacturing overhead costs. Many managers believe that such fluctuations in product costs serve

no useful purpose. To avoid such fluctuations, actual overhead rates could be computed
on an annual or less-frequent basis. However, if the overhead rate is computed annually
based on the actual costs and activity for the year, the manufacturing overhead assigned
to any particular job would not be known until the end of the year. For example, the cost
of Job 2B47 at Yost Precision Machining would not be known until the end of the year,
even though the job will be completed and shipped to the customer in March. For these
reasons, most companies use predetermined overhead rates rather than actual overhead
rates in their cost accounting systems.
Choice of an Allocation Base for Overhead Cost
Ideally, the allocation base in the predetermined overhead rate should drive the overhead
cost. A cost driver is a factor, such as machine-hours, beds occupied, computer time, or
flight-hours, that causes overhead costs. If the base in the predetermined overhead rate
does not “drive” overhead costs, product costs will be distorted. For example, if direct
labor-hours is used to allocate overhead, but in reality overhead has little to do with direct
labor-hours, then products with high direct labor-hour requirements will be overcosted.
Most companies use direct labor-hours or direct labor cost as the allocation base
for manufacturing overhead. In the past, direct labor accounted for up to 60% of the
cost of many products, with overhead cost making up only a portion of the remainder.
This situation has changed for two reasons. First, sophisticated automated equipment
has taken over functions that used to be performed by direct labor workers. Because
the costs of acquiring and maintaining such equipment are classified as overhead, this
increases overhead while decreasing direct labor. Second, products are becoming more
92
Chapter 3
sophisticated and complex and are changed more frequently. This increases the need for
highly skilled indirect workers such as engineers. As a result of these two trends, direct
labor has decreased relative to overhead as a component of product costs.
In companies where direct labor and overhead costs have been moving in opposite
directions, it would be difficult to argue that direct labor “drives” overhead costs. Accordingly, managers in some companies use activity-based costing principles to redesign their
cost accounting systems. Activity-based costing is designed to more accurately reflect the
demands that products, customers, and other cost objects make on overhead resources.
The activity-based approach is discussed in more detail in Appendix 3A and in Chapter 7.
Although direct labor may not be an appropriate allocation base in some industries,
in others it continues to be a significant driver of manufacturing overhead. Indeed, most
manufacturing companies in the United States continue to use direct labor as the primary
or secondary allocation base for manufacturing overhead. The key point is that the allocation base used by the company should really drive, or cause, overhead costs, and direct
labor is not always the most appropriate allocation base.

REDUCING HEALTH-DAMAGING BEHAVIORS
Cianbro is an industrial construction company headquartered in Pittsfield, Maine, whose goal is “To be
the healthiest company in America.” It introduced a corporate wellness program to attack employee
behaviors that drive up health-care costs. The table below summarizes the number of employees in
five health risk categories as of 2003 and 2005. The decreases in the number of employees in these
high-risk categories are evidence that the wellness program was effective in helping employees
make positive lifestyle changes. This should result in reduced health-care costs for the company.

Computation of Unit Costs
Compute the total cost and
average cost per unit of a job.
With the application of Yost Precision Machining’s $216 of manufacturing overhead to
the job cost sheet in Exhibit 3–4, the job cost sheet is complete except for two final steps.
First, the totals for direct materials, direct labor, and manufacturing overhead are transferred to the Cost Summary section of the job cost sheet and added together to obtain the
total cost for the job.1 Then the total product cost ($1,800) is divided by the number of
units (2) to obtain the unit product cost ($900). This unit product cost information is used
for valuing unsold units in ending inventory and for determining cost of goods sold. As
indicated earlier, this unit product cost is an average cost and should not be interpreted
as the cost that would actually be incurred if another unit were produced. The incremental cost of an additional unit is something less than the average unit cost of $900 because
much of the actual overhead costs would not change if another unit were produced.

Notice, we are assuming that Job 2B47 required direct materials and direct labor beyond the charges
shown in Exhibits 3–1 and 3–3.

Jean: I see Job 2B47 is completed. Let’s get those couplings shipped immediately to
Loops Unlimited so they can get their testing program under way. Marc, how much
are we going to bill Loops for those two units?
Marc: Because we agreed to sell the experimental couplings at cost, we will be charging Loops Unlimited just $900 a unit.
Jean: Fine. Let’s hope the couplings work out and we make some money on the big
order later.
THE WRAP-UP
IN BUSINESS
ONE-OF-A-KIND MASTERPIECE
In a true job-order costing environment, every job is unique. For example, Purdey manufactures
80–90 shotguns per year with each gun being a specially commissioned one-of-a-kind masterpiece.
The prices start at $110,000 because every detail is custom built, engraved, assembled, and
polished by a skilled craftsman. The hand engraving can take months to complete and may add as
much as $100,000 to the price. The guns are designed to shoot perfectly straight and their value
increases over time even with heavy use. One Purdey gun collector said “when I shoot my Purdeys
I feel like an orchestra conductor waving my baton.”

Job-Order Costing—The Flow of Costs
We are now ready to discuss the flow of costs through a job-order costing system.
Exhibit 3–5 provides a conceptual overview of these cost flows. It highlights the fact that
product costs flow through inventories on the balance sheet and then on to cost of goods
sold in the income statement. More specifically, raw materials purchases are recorded in
the Raw Materials inventory account. Raw materials include any materials that go into
the final product. When raw materials are used in production, their costs are transferred
to the Work in Process inventory account as direct materials.2 Work in process consists
of units of product that are only partially complete and will require further work before
they are ready for sale to the customer. Notice that direct labor costs are added directly
to Work in Process—they do not flow through Raw Materials inventory. Manufacturing
overhead costs are applied to Work in Process by multiplying the predetermined overhead
rate by the actual quantity of the allocation base consumed by each job.3 When goods are
completed, their costs are transferred from Work in Process to Finished Goods. Finished
goods consist of completed units of product that have not yet been sold to customers.
The amount transferred from Work in Process to Finished Goods is referred to as the cost
of goods manufactured. The cost of goods manufactured includes the manufacturing
costs associated with the goods that were finished during the period. As goods are sold,
their costs are transferred from Finished Goods to Cost of Goods Sold. At this point, the
various costs required to make the product are finally recorded as an expense. Until that
point, these costs are in inventory accounts on the balance sheet. Period costs (or selling
and administrative expenses) do not flow through inventories on the balance sheet. They
are recorded as expenses on the income statement in the period incurred.
2
Indirect material costs are accounted for as part of manufacturing overhead.
For simplicity, Exhibit 3–5 assumes that Cost of Goods Sold does not need to be adjusted as discussed
later in the chapter.

To illustrate the cost flows through a company’s general ledger, we will consider a
single month’s activity at Ruger Corporation, a producer of gold and silver commemorative medallions. Ruger Corporation has two jobs in process during April, the first month
of its fiscal year. Job A, a special minting of 1,000 gold medallions commemorating the
invention of motion pictures, was started during March. By the end of March, $30,000
in manufacturing costs had been recorded for the job. Job B, an order for 10,000 silver
medallions commemorating the fall of the Berlin Wall, was started in April.
The Purchase and Issue of Materials
On April 1, Ruger Corporation had $7,000 in raw materials on hand. During the month,
the company purchased on account an additional $60,000 in raw materials. The purchase
is recorded in journal entry (1) below:

Remember that Raw Materials is an asset account. Thus, when raw materials are
purchased, they are initially recorded as an asset—not as an expense.
Issue of Direct and Indirect Materials During April, $52,000 in raw materials were requisitioned from the storeroom for use in production. These raw materials
included $50,000 of direct and $2,000 of indirect materials. Entry (2) records issuing the

The materials charged to Work in Process represent direct materials for specific jobs.
These costs are also recorded on the appropriate job cost sheets. This point is illustrated
in Exhibit 3–6, where $28,000 of the $50,000 in direct materials is charged to Job A’s cost
sheet and the remaining $22,000 is charged to Job B’s cost sheet. (In this example, all
data are presented in summary form and the job cost sheet is abbreviated.)
The $2,000 charged to Manufacturing Overhead in entry (2) represents indirect
materials. Observe that the Manufacturing Overhead account is separate from the Work
in Process account. The purpose of the Manufacturing Overhead account is to accumulate
all manufacturing overhead costs as they are incurred during a period.
Before leaving Exhibit 3–6, we need to point out one additional thing. Notice from
the exhibit that the job cost sheet for Job A contains a beginning balance of $30,000. We
stated earlier that this balance represents the cost of work done during March that has
been carried forward to April. Also note that the Work in Process account contains the
same $30,000 balance. Thus, the Work in Process account summarizes all of the costs
appearing on the job cost sheets of the jobs that are in process. Job A was the only job
in process at the beginning of April, so the beginning balance in the Work in Process
account equals Job A’s beginning balance of $30,000.
Labor Cost
In April, the employee time tickets included $60,000 recorded for direct labor and
$15,000 for indirect labor. The following entry summarizes these costs:

Salaries and Wages Payable . . . . . . . . . . . . . . . . . . . . . . . . .
75,000
Only the direct labor cost of $60,000 is added to the Work in Process account. At the
same time that direct labor costs are added to Work in Process, they are also added to the
individual job cost sheets, as shown in Exhibit 3–7. During April, $40,000 of direct labor
cost was charged to Job A and the remaining $20,000 was charged to Job B.
The labor costs charged to Manufacturing Overhead ($15,000) represent the indirect
labor costs of the period, such as supervision, janitorial work, and maintenance.

Job-Order Costing
In short, all actual manufacturing overhead costs are debited to the Manufacturing
Overhead account as they are incurred.
Applying Manufacturing Overhead
Because actual manufacturing costs are charged to the Manufacturing Overhead control
account rather than to Work in Process, how are manufacturing overhead costs assigned
to Work in Process? The answer is, by means of the predetermined overhead rate. Recall
from our discussion earlier in the chapter that a predetermined overhead rate is established at the beginning of each year. The rate is calculated by dividing the estimated total
manufacturing overhead cost for the year by the estimated total amount of the allocation
base (measured in machine-hours, direct labor-hours, or some other base). The predetermined overhead rate is then used to apply overhead costs to jobs. For example, if
machine-hours is the allocation base, overhead cost is applied to each job by multiplying
the predetermined overhead rate by the number of machine-hours charged to the job.
To illustrate, assume that Ruger Corporation’s predetermined overhead rate is $6 per
machine-hour. Also assume that during April, 10,000 machine-hours were worked on Job
A and 5,000 machine-hours were worked on Job B (a total of 15,000 machine-hours). Thus,
$90,000 in overhead cost ($6 per machine-hour 3 15,000 machine-hours 5 $90,000)
would be applied to Work in Process. The following entry records the application of Manufacturing Overhead to Work in Process:

Manufacturing Overhead . . . . . . . . . . . . . . . . . . . . . . . . . . . .
90,000
The flow of costs through the Manufacturing Overhead account is shown in Exhibit 3–8.
The actual overhead costs on the debit side in the Manufacturing Overhead account in
Exhibit 3–8 are the costs that were added to the account in entries (2)–(6). Observe that
recording these actual overhead costs [entries (2)–(6)] and the application of overhead to
Work in Process [entry (7)] represent two separate and entirely distinct processes.
The Concept of a Clearing Account The Manufacturing Overhead account
operates as a clearing account. As we have noted, actual factory overhead costs are debited to the account as they are incurred throughout the year. When a job is completed (or
at the end of an accounting period), overhead cost is applied to the job using the predetermined overhead rate, and Work in Process is debited and Manufacturing Overhead is
credited. This sequence of events is illustrated below:
Manufacturing Overhead
(a clearing account)
Actual overhead costs are charged
to this account as they are incurred
throughout the period.
Overhead is applied to Work in Process
using the predetermined overhead rate.
As we emphasized earlier, the predetermined overhead rate is based entirely on estimates of what the level of activity and overhead costs are expected to be, and it is established before the year begins. As a result, the overhead cost applied during a year will
almost certainly turn out to be more or less than the actual overhead cost incurred. For
example, notice from Exhibit 3–8 that Ruger Corporation’s actual overhead costs for the
period are $5,000 greater than the overhead cost that has been applied to Work in Process, resulting in a $5,000 debit balance in the Manufacturing Overhead account. We will
reserve discussion of what to do with this $5,000 balance until later in the chapter.
For the moment, we can conclude from Exhibit 3–8 that the cost of a completed job
consists of the actual direct materials cost of the job, the actual direct labor cost of the
job, and the manufacturing overhead cost applied to the job. Pay particular attention to
the following subtle but important point: Actual overhead costs are not charged to jobs;

in Process account. Only the applied overhead cost, based on the predetermined overhead rate, appears on the job cost sheet and in the Work in Process account.
Nonmanufacturing Costs
In addition to manufacturing costs, companies also incur selling and administrative costs.
These costs should be treated as period expenses and charged directly to the income
statement. Nonmanufacturing costs should not go into the Manufacturing Overhead
account. To illustrate the correct treatment of nonmanufacturing costs, assume that Ruger
Corporation incurred $30,000 in selling and administrative salary costs during April. The
following entry summarizes the accrual of those salaries:
(8)
Salaries Expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30,000
Salaries and Wages Payable . . . . . . . . . . . . . . . . . . . . . . . . .
30,000
Assume that depreciation on office equipment during April was $7,000. The entry is
as follows:
(9)
Depreciation Expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Accumulated Depreciation . . . . . . . . . . . . . . . . . . . . . . . . . .
7,000
7,000
Pay particular attention to the difference between this entry and entry (6) where we
recorded depreciation on factory equipment. In journal entry (6), depreciation on factory equipment was debited to Manufacturing Overhead and is therefore a product cost.
In journal entry (9) above, depreciation on office equipment is debited to Depreciation
Expense. Depreciation on office equipment is a period expense rather than a product cost.
Finally, assume that advertising was $42,000 and that other selling and administrative expenses in April totaled $8,000. The following entry records these items:
Job-Order Costing
(10)
Advertising Expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 42,000

Accounts Payable* . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
50,000
*Other accounts, such as Cash may be credited.
The amounts in entries (8) through (10) are recorded directly into expense accounts—
they have no effect on product costs. The same will be true of any other selling and administrative expenses incurred during April, including sales commissions, depreciation on
sales equipment, rent on office facilities, insurance on office facilities, and related costs.
Cost of Goods Manufactured
When a job has been completed, the finished output is transferred from the production
departments to the finished goods warehouse. By this time, the accounting department
will have charged the job with direct materials and direct labor cost, and manufacturing
overhead will have been applied using the predetermined overhead rate. A transfer of costs
is made within the costing system that parallels the physical transfer of goods to the finished goods warehouse. The costs of the completed job are transferred out of the Work in
Process account and into the Finished Goods account. The sum of all amounts transferred
between these two accounts represents the cost of goods manufactured for the period.
In the case of Ruger Corporation, assume that Job A was completed during April.
The following entry transfers the cost of Job A from Work in Process to Finished Goods:
(11)
Finished Goods . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 158,000
Work in Process . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
158,000
The $158,000 represents the completed cost of Job A, as shown on the job cost sheet in
Exhibit 3–8. Because Job A was the only job completed during April, the $158,000 also
represents the cost of goods manufactured for the month.
Job B was not completed by the end of the month, so its cost will remain in the Work
in Process account and carry over to the next month. If a balance sheet is prepared at the
end of April, the cost accumulated thus far on Job B will appear as the asset “Work in
Process inventory.”
Cost of Goods Sold
As finished goods are shipped to customers, their accumulated costs are transferred from
the Finished Goods account to the Cost of Goods Sold account. If an entire job is shipped
at one time, then the entire cost appearing on the job cost sheet is transferred to the Cost
of Goods Sold account. In most cases, however, only a portion of the units involved in a
particular job will be immediately sold. In these situations, the unit product cost must be
used to determine how much product cost should be removed from Finished Goods and
charged to Cost of Goods Sold.
For Ruger Corporation, we will assume 750 of the 1,000 gold medallions in Job A
were shipped to customers by the end of the month for total sales revenue of $225,000.
Because 1,000 units were produced and the total cost of the job from the job cost sheet
was $158,000, the unit product cost was $158. The following journal entries would record
the sale (all sales were on account):

Schedules of Cost of Goods Manufactured and Cost of Goods Sold
LO3–6
Prepare schedules of cost of
goods manufactured and cost
of goods sold and an income
statement.
This section uses the Ruger Corporation example to explain how to prepare schedules of cost of goods manufactured and cost of goods sold as well as an income statement. The schedule of cost of goods manufactured contains three elements of product
costs—direct materials, direct labor, and manufacturing overhead—and it summarizes
the portions of those costs that remain in ending Work in Process inventory and that are
transferred out of Work in Process into Finished Goods. The schedule of cost of goods
sold also contains three elements of product costs—direct materials, direct labor, and
manufacturing overhead—and it summarizes the portions of those costs that remain in
ending Finished Goods inventory and that are transferred out of Finished Goods into Cost
of Goods Sold.
Exhibit 3–11 presents Ruger Corporation’s schedules of cost of goods manufactured
and cost of goods sold. We want to draw your attention to three equations that are embedded within the schedule of cost of goods manufactured. First, the raw materials used in
production are computed using the following equation:
Raw materials 5 ________________

For Ruger Corporation, the beginning raw materials inventory of $7,000 plus the purchases of raw materials of $60,000 minus the ending raw materials inventory of $15,000

equals the raw materials used in production of $52,000. Second, the total manufacturing
costs are computed using the following equation:
Total
Manufacturing
manufacturing 5 Direct materials 1 Direct labor 1 overhead applied to
costs
work in process
For Ruger Corporation, the direct materials of $50,000 plus the direct labor of
$60,000 plus the manufacturing overhead applied to work in process of $90,000
equals the total manufacturing costs of $200,000. Notice, the direct materials used in
production ($50,000) is included in total manufacturing costs instead of raw materials purchases ($60,000). The direct materials used in production will usually differ
from the amount of raw material purchases when the raw materials inventory balance
changes or indirect materials are withdrawn from raw materials inventory. You should
also make a note that this equation includes manufacturing overhead applied to work
in process rather than actual manufacturing overhead costs. For Ruger Corporation,
its manufacturing overhead applied to work in process of $90,000 is computed by
multiplying the predetermined overhead rate of $6 per machine-hour by the actual
amount of the allocation base recorded on all jobs, or 15,000 machine-hours. The
actual manufacturing overhead costs incurred during the period are not added to the
Work in Process account.
The third equation included in the schedule of cost of goods manufactured relates to
computing the cost of goods manufactured:
Cost of goods

Ending work in

manufactured manufacturing costs

For Ruger, the total manufacturing costs of $200,000 plus the beginning work in process
inventory of $30,000 minus the ending work in process inventory of $72,000 equals the
cost of goods manufactured of $158,000. The cost of goods manufactured represents the
cost of the goods completed during the period and transferred from Work in Process to
Finished Goods.
The schedule of cost of goods sold shown in Exhibit 3–11 relies on the following
equation to compute the unadjusted cost of goods sold:
Unadjusted cost Beginning finished Cost of goods Ending finished

manufactured goods inventory
The beginning finished goods inventory ($10,000) plus the cost of goods manufactured ($158,000) equals the cost of goods available for sale ($168,000). The cost
of goods available for sale ($168,000) minus the ending finished goods inventory
($49,500) equals the unadjusted cost of goods sold ($118,500). Finally, the unadjusted cost of goods sold ($118,500) plus the underapplied overhead ($5,000) equals
adjusted cost of goods sold ($123,500). The next section of the chapter takes a closer
look at why cost of goods sold needs to be adjusted for the amount of underapplied or
overapplied overhead.
Exhibit 3–12 presents Ruger Corporation’s income statement for April. Observe that
the cost of goods sold on this statement is carried over from Exhibit 3–11. The selling and
administrative expenses (which total $87,000) did not flow through the schedules of cost
of goods manufactured and cost of goods sold. Journal entries 8–10 (pages 98–99) show
that these items were immediately debited to expense accounts rather than being debited
to inventory accounts.

Underapplied and Overapplied Overhead—A Closer Look
LO3–7
Compute underapplied or
overapplied overhead cost
and prepare the journal
entry to close the balance in
Manufacturing Overhead to the
appropriate accounts.
This section explains how to compute underapplied and overapplied overhead and how
to dispose of any balance remaining in the Manufacturing Overhead account at the end
of a period.
Computing Underapplied and Overapplied Overhead
Because the predetermined overhead rate is established before the period begins and is
based entirely on estimated data, the overhead cost applied to Work in Process will generally differ from the amount of overhead cost actually incurred. In the case of Ruger
Corporation, for example, the predetermined overhead rate of $6 per hour was used to
apply $90,000 of overhead cost to Work in Process, whereas actual overhead costs for
April proved to be $95,000 (see Exhibit 3–8). The difference between the overhead cost
applied to Work in Process and the actual overhead costs of a period is called either
underapplied or overapplied overhead. For Ruger Corporation, overhead was underapplied by $5,000 because the applied cost ($90,000) was $5,000 less than the actual cost
($95,000). If the situation had been reversed and the company had applied $95,000 in
overhead cost to Work in Process while incurring actual overhead costs of only $90,000,
then the overhead would have been overapplied.
What is the cause of underapplied or overapplied overhead? Basically, the method of
applying overhead to jobs using a predetermined overhead rate assumes that actual overhead costs will be proportional to the actual amount of the allocation base incurred during
the period. If, for example, the predetermined overhead rate is $6 per machine-hour, then
it is assumed that actual overhead costs incurred will be $6 for every machine-hour that is
actually worked. There are at least two reasons why this may not be true. First, much of
the overhead often consists of fixed costs that do not change as the number of machinehours incurred goes up or down. Second, spending on overhead items may or may not be
under control. If individuals who are responsible for overhead costs do a good job, those
costs should be less than were expected at the beginning of the period. If they do a poor
job, those costs will be more than expected.
To illustrate these concepts, suppose that two companies—Turbo Crafters and
Black & Howell—have prepared the following estimated data for the coming year:
Turbo Crafters
Allocation base . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Estimated manufacturing overhead cost (a) . . . . . . . . .

75,000 machine-hours
$80,000 direct materials cost
$4 per machine-hour
150% of direct materials cost
Job-Order Costing
105
Note that when the allocation base is dollars (such as direct materials cost in the case
of Black & Howell) the predetermined overhead rate is expressed as a percentage of the
allocation base. When dollars are divided by dollars, the result is a percentage.
Now assume that because of unexpected changes in overhead spending and in
demand for the companies’ products, the actual overhead cost and the actual activity
recorded during the year in each company are as follows:
Turbo Crafters
Actual manufacturing overhead cost . . . . . . . . . . . . . . . .
Actual total amount of the allocation base . . . . . . . . . . . .
$290,000
68,000 machine-hours
Black & Howell
$130,000
$90,000 direct materials cost
For each company, note that the actual data for both cost and the allocation base differ from the estimates used in computing the predetermined overhead rate. This results in
underapplied and overapplied overhead as follows:
Turbo Crafters
Actual manufacturing overhead cost . . . . . . . . . . . . . . . .
Manufacturing overhead cost applied to
Work in Process during the year:
Predetermined overhead rate (a) . . . . . . . . . . . . . . . . . .

68,000 machine-hours
$90,000 direct materials cost
$272,000
$135,000
$18,000
$(5,000)
For Turbo Crafters, the amount of overhead cost applied to Work in Process
($272,000) is less than the actual overhead cost for the year ($290,000). Therefore, overhead is underapplied.
For Black & Howell, the amount of overhead cost applied to Work in Process
($135,000) is greater than the actual overhead cost for the year ($130,000), so overhead
is overapplied.
A summary of these concepts is presented in Exhibit 3–13.

Chapter 3
Disposition of Underapplied or Overapplied
Overhead Balances
If we return to the Ruger Corporation example and look at the Manufacturing Overhead
T-account in Exhibit 3–10, you will see that there is a debit balance of $5,000. Remember that debit entries to the account represent actual overhead costs incurred, whereas
credit entries represent overhead costs applied to jobs. In this case, the actual overhead
costs incurred exceeded the overhead costs applied to jobs by $5,000—hence, the debit
balance of $5,000. This may sound familiar. We just discussed in the previous section
the fact that the overhead costs incurred ($95,000) exceeded the overhead costs applied
($90,000), and that the difference is called underapplied overhead. These are just two
ways of looking at the same thing. If there is a debit balance in the Manufacturing Overhead account of X dollars, then the overhead is underapplied by X dollars. On the other
hand, if there is a credit balance in the Manufacturing Overhead account of Y dollars,
then the overhead is overapplied by Y dollars. What do we do with the balance in the
Manufacturing Overhead account at the end of the accounting period?
The underapplied or overapplied balance remaining in the Manufacturing Overhead
account at the end of a period is treated in one of two ways:
1. Closed out to Cost of Goods Sold.
2. Allocated among the Work in Process, Finished Goods, and Cost of Goods Sold
accounts in proportion to the overhead applied during the current period in ending
balances.
Closed Out to Cost of Goods Sold Closing out the balance in Manufacturing Overhead to Cost of Goods Sold is simpler than the allocation method. In the Ruger
Corporation example, the entry to close the $5,000 of underapplied overhead to Cost of
Goods Sold is:
(14)
Cost of Goods Sold . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5,000
Manufacturing Overhead . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
5,000
Note that because the Manufacturing Overhead account has a debit balance, Manufacturing Overhead must be credited to close out the account. This has the effect of increasing
Cost of Goods Sold for April to $123,500:
Unadjusted cost of goods sold [from entry (13)] . . . . . . .
Add underapplied overhead [from entry (14)] . . . . . . . . . .
Adjusted cost of goods sold . . . . . . . . . . . . . . . . . . . . . .
$118,500
5,000
$123,500
After this adjustment has been made, Ruger Corporation’s income statement for April
will appear as shown earlier in Exhibit 3–12.
Note that this adjustment makes sense. The unadjusted cost of goods sold is based on
the amount of manufacturing overhead applied to jobs, not the manufacturing overhead
costs actually incurred. Because overhead was underapplied, not enough cost was applied
to jobs. Hence, the cost of goods sold was understated. Adding the underapplied overhead
to the cost of goods sold corrects this understatement.
Allocated between Accounts Allocation of underapplied or overapplied overhead between Work in Process, Finished Goods, and Cost of Goods Sold is more accurate
than closing the entire balance into Cost of Goods Sold. This allocation assigns overhead
costs to where they would have gone had the estimates included in the predetermined
overhead rate matched the actual amounts.
Had Ruger Corporation chosen to allocate the underapplied overhead among the
inventory accounts and Cost of Goods Sold, it would first be necessary to determine the
Job-Order Costing
amount of overhead that had been applied during April to each of the accounts. The computations would have been as follows:
Overhead applied in work in process inventory, April 30 (Job B) . . . $30,000 33.33%
Overhead applied in finished goods inventory, April 30
Job A: ($60,000/1,000 units 5 $60 per unit) 3 250 units . . . . . . . 15,000 16.67%
Overhead applied in cost of goods sold, April
Job A: ($60,000/1,000 units 5 $60 per unit) 3 750 units . . . . . . . 45,000 50.00%
Total overhead applied . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $90,000 100.00%
Based on the above percentages, the underapplied overhead (i.e., the debit balance in
Manufacturing Overhead) would be allocated as shown in the following journal entry:
Work in Process (33.33% 3 $5,000) . . . . . . . . . . . . . . . . . 1,666.50
Finished Goods (16.67% 3 $5,000) . . . . . . . . . . . . . . . . .
833.50
Cost of Goods Sold (50.00% 3 $5,000) . . . . . . . . . . . . . . 2,500.00
Manufacturing Overhead . . . . . . . . . . . . . . . . . . . . . . . .
5,000.00
Note that the first step in the allocation process was to determine the amount of overhead
applied in each of the accounts. For Finished Goods, for example, the total amount of
overhead applied to Job A, $60,000, was divided by the total number of units in Job A,
1,000 units, to arrive at the average overhead applied of $60 per unit. Because 250 units
from Job A were still in ending finished goods inventory, the amount of overhead applied
in the Finished Goods Inventory account was $60 per unit multiplied by 250 units or
$15,000 in total.
If overhead had been overapplied, the entry above would have been just the reverse,
because a credit balance would have existed in the Manufacturing Overhead account.
Which Method Should Be Used for Disposing of Underapplied or Overapplied Overhead?
The allocation method is generally considered more accurate than simply closing out the
underapplied or overapplied overhead to Cost of Goods Sold. However, the allocation
method is more complex. We will always specify which method you are to use in problem assignments.
A General Model of Product Cost Flows
Exhibit 3–14 presents a T-account model of the flow of costs in a product costing system.
This model can be very helpful in understanding how production costs flow through a
costing system and finally end up as Cost of Goods Sold on the income statement.
Multiple Predetermined Overhead Rates
Our discussion in this chapter has assumed that there is a single predetermined overhead
rate for an entire factory called a plantwide overhead rate. This is a fairly common
practice—particularly in smaller companies. But in larger companies, multiple predetermined overhead rates are often used. In a multiple predetermined overhead rate
system each production department may have its own predetermined overhead rate. Such
a system, while more complex, is more accurate because it can reflect differences across
departments in how overhead costs are incurred. For example, in departments that are
relatively labor intensive overhead might be allocated based on direct labor-hours and
in departments that are relatively machine intensive overhead might be allocated based
on machine-hours. When multiple predetermined overhead rates are used, overhead is
applied in each department according to its own overhead rate as jobs proceed through
the department.

Job-Order Costing in Service Companies
Job-order costing is used in service organizations such as law firms, movie studios,
hospitals, and repair shops, as well as in manufacturing companies. In a law firm, for
example, each client is a “job,” and the costs of that job are accumulated day by day
on a job cost sheet as the client’s case is handled by the firm. Legal forms and similar
inputs represent the direct materials for the job; the time expended by attorneys is like
direct labor; and the costs of secretaries and legal aids, rent, depreciation, and so forth,
represent the overhead.
In a movie studio such as Columbia Pictures, each film produced by the studio is a
“job,” and costs of direct materials (costumes, props, film, etc.) and direct labor (actors,
directors, and extras) are charged to each film’s job cost sheet. A share of the studio’s
overhead costs, such as utilities, depreciation of equipment, wages of maintenance workers, and so forth, is also charged to each film.
In sum, job-order costing is a versatile and widely used costing method that may be
encountered in virtually any organization that provides diverse products or services.

IN BUSINESS
COMPUTING JOB COSTS AT FAST WRAP
In 2007, Michael Enos founded Fast Wrap, a company that shrink-wraps everything from jet skis and
recreation vehicles (RVs) to entire buildings. Today, the company has 64 locations across America and
generates more than $6 million in annual sales. The company’s revenues far exceed its direct materials and direct labor costs. For example, Fast Wrap charges customers $400 to wrap a 20-foot boat
that requires $25 worth of plastic and $30 worth of labor. Larger jobs are even more profitable. For
example, Fast Wrap signed a $250,000 contract to shrink-wrap a 244,000-square-foot hospital under
construction in Fontana, California. The materials and labor for this job cost Fast Wrap $44,000.

Summary
Job-order costing is used in situations where the organization offers many different products or services, such as in furniture manufacturing, hospitals, and legal firms. Materials requisition forms and
labor time tickets are used to assign direct materials and direct labor costs to jobs in a job-order
costing system. Manufacturing overhead costs are assigned to jobs using a predetermined overhead
rate. All of the costs are recorded on a job cost sheet. The predetermined overhead rate is determined
before the period begins by dividing the estimated total manufacturing overhead cost for the period
by the estimated total amount of the allocation base for the period. The most frequently used allocation bases are direct labor-hours and machine-hours. Overhead is applied to jobs by multiplying the
predetermined overhead rate by the actual amount of the allocation base recorded for the job.
Because the predetermined overhead rate is based on estimates, the actual overhead cost
incurred during a period may be more or less than the amount of overhead cost applied to production. Such a difference is referred to as underapplied or overapplied overhead. The underapplied or overapplied overhead for a period can be either closed out to Cost of Goods Sold or
allocated between Work in Process, Finished Goods, and Cost of Goods Sold. When overhead is
underapplied, manufacturing overhead costs have been understated and therefore inventories and/
or expenses must be adjusted upwards. When overhead is overapplied, manufacturing overhead
costs have been overstated and therefore inventories and/or expenses must be adjusted downwards.
Review Problem: Job-Order Costing

$20,000
$15,000
$30,000
The company applies overhead cost to jobs on the basis of machine-hours worked. For the
current year, the company’s predetermined overhead rate was based on a cost formula that estimated $450,000 of total manufacturing overhead for an estimated activity level of 75,000 machinehours. The following transactions were recorded for the year:
a. Raw materials were purchased on account, $410,000.
b. Raw materials were requisitioned for use in production, $380,000 ($360,000 direct materials
and $20,000 indirect materials).
c. The following costs were accrued for employee services: direct labor, $75,000; indirect labor,
$110,000; sales commissions, $90,000; and administrative salaries, $200,000.
d. Sales travel costs were $17,000.
e. Utility costs in the factory were $43,000.

Chapter 3
Leeds Architectural Consultants is a service firm, so the names of the accounts it uses are
different from the names used in manufacturing companies. Costs of Subcontracted Work is comparable to Direct Materials; Direct Staff Costs is the same as Direct Labor; Studio Overhead is the
same as Manufacturing Overhead; and Completed Projects is the same as Finished Goods. Apart
from the difference in terms, the accounting methods used by the company are identical to the
methods used by manufacturing companies.
Leeds Architectural Consultants uses a job-order costing system and applies studio overhead to Work in Process on the basis of direct staff costs. At the end of January, only one job was
still in process. This job (Lexington Gardens Project) had been charged with $6,500 in direct
staff costs.

Because the videos differ in length and in complexity of production, the company uses a joborder costing system to determine the cost of each video produced. Studio (manufacturing) overhead is charged to videos on the basis of camera-hours of activity. The company’s predetermined
overhead rate for the year is based on a cost formula that estimated $280,000 in manufacturing
overhead for an estimated allocation base of 7,000 camera-hours. The following transactions were
recorded for the year:
a. Film, costumes, and similar raw materials purchased on account, $185,000.
b. Film, costumes, and other raw materials issued to production, $200,000 (85% of this material
was considered direct to the videos in production, and the other 15% was considered indirect).
c. Utility costs incurred in the production studio, $72,000.
d. Depreciation recorded on the studio, cameras, and other equipment, $84,000. Three-fourths
of this depreciation related to actual production of the videos, and the remainder related to
equipment used in marketing and administration.
e. Advertising expense incurred, $130,000.
f. Costs for salaries and wages were incurred as follows:
Direct labor (actors and directors) . . . . . . . . . . .
Indirect labor (carpenters to build sets,
costume designers, and so forth) . . . . . . . . . .

CASE 3–29 Ethics and the Manager [LO3–1, LO3–2, LO3–7]
Terri Ronsin had recently been transferred to the Home Security Systems Division of National
Home Products. Shortly after taking over her new position as divisional controller, she was asked
to develop the division’s predetermined overhead rate for the upcoming year. The accuracy of the
rate is important because it is used throughout the year and any overapplied or underapplied overhead is closed out to Cost of Goods Sold at the end of the year. National Home Products uses direct
labor-hours in all of its divisions as the allocation base for manufacturing overhead.
To compute the predetermined overhead rate, Terri divided her estimate of the total manufacturing overhead for the coming year by the production manager’s estimate of the total direct
labor-hours for the coming year. She took her computations to the division’s general manager for
approval but was quite surprised when he suggested a modification in the base. Her conversation
with the general manager of the Home Security Systems Division, Harry Irving, went like this:
Ronsin: Here are my calculations for next year’s predetermined overhead rate. If you approve, we can
enter the rate into the computer on January 1 and be up and running in the job-order costing system
right away this year.
Irving: Thanks for coming up with the calculations so quickly, and they look just fine. There is, however, one slight modification I would like to see. Your estimate of the total direct labor-hours for the
year is 440,000 hours. How about cutting that to about 420,000 hours?
Ronsin: I don’t know if I can do that. The production manager says she will need about 440,000 direct
labor-hours to meet the sales projections for the year. Besides, there are going to be over 430,000
direct labor-hours during the current year and sales are projected to be higher next year.
Irving: Teri, I know all of that. I would still like to reduce the direct labor-hours in the base to something like 420,000 hours. You probably don’t know that I had an agreement with your predecessor
as divisional controller to shave 5% or so off the estimated direct labor-hours every year. That way,
we kept a reserve that usually resulted in a big boost to net operating income at the end of the fiscal year in December. We called it our Christmas bonus. Corporate headquarters always seemed
as pleased as punch that we could pull off such a miracle at the end of the year. This system has
worked well for many years, and I don’t want to change it now.

Should Terri Ronsin go along with the general manager’s request to reduce the direct laborhours in the predetermined overhead rate computation to 420,000 direct labor-hours?
CASE 3–30 Plantwide versus Departmental Overhead Rates; Underapplied or Overapplied Overhead
[LO3–1, LO3–2, LO3–3, LO3–7]
“Blast it!” said David Wilson, president of Teledex Company. “We’ve just lost the bid on the Koopers job by $2,000. It seems we’re either too high to get the job or too low to make any money on
half the jobs we bid.”

Assuming use of a plantwide overhead rate:
a. Compute the rate for the current year.
b. Determine the amount of manufacturing overhead cost that would have been applied to
the Koopers job.
Suppose that instead of using a plantwide overhead rate, the company had used a separate
predetermined overhead rate in each department. Under these conditions:
a. Compute the rate for each department for the current year.
b. Determine the amount of manufacturing overhead cost that would have been applied to
the Koopers job.
Explain the difference between the manufacturing overhead that would have been applied to
the Koopers job using the plantwide rate in question 1 (b) and using the departmental rates in
question 2 (b).
Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost
(direct materials, direct labor, and applied overhead). What was the company’s bid price on
the Koopers job? What would the bid price have been if departmental overhead rates had been
used to apply overhead cost?
At the end of the year, the company assembled the following actual cost data relating to all
jobs worked on during the year.

Appendix 3A: Activity-Based Absorption Costing
LO3–8
Use activity-based absorption
costing to compute unit
product costs.
Chapter 3 described how manufacturing companies use traditional absorption costing systems to calculate unit product costs for the purpose of valuing inventories and determining
cost of goods sold for external financial reports. In this appendix, we contrast traditional
absorption costing with an alternative approach called activity-based absorption costing.
Activity-based absorption costing assigns all manufacturing overhead costs to products based on the activities performed to make those products. An activity is an event that
Job-Order Costing
131
causes the consumption of manufacturing overhead resources. Rather than relying on plantwide or departmental cost pools, the activity-based approach accumulates each activity’s
overhead costs in activity cost pools. An activity cost pool is a “bucket” in which costs are
accumulated that relate to a single activity. Each activity cost pool has one activity measure.
An activity measure is an allocation base that is used as the denominator for an activity
cost pool. The costs accumulated in the numerator of an activity cost pool divided by the
quantity of the activity measure in its denominator equals what is called an activity rate. An
activity rate is used to assign costs from an activity cost pool to products.
Activity-based absorption costing differs from traditional absorption costing in two
ways. First, the activity-based approach uses more cost pools than a traditional approach.
Second, the activity-based approach includes some activities and activity measures that
do not relate to the volume of units produced, whereas the traditional approach relies
exclusively on allocation bases that are driven by the volume of production. For example,
the activity-based approach may include batch-level activities. A batch-level activity is
performed each time a batch is handled or processed, regardless of how many units are
in the batch. Batch-level activities include tasks such as placing purchase orders, setting up equipment, and transporting batches of component parts. Costs at the batch level
depend on the number of batches processed rather than the number of units produced.
The activity-based approach may also include product-level activities. A product-level
activity relates to specific products and typically must be carried out regardless of how
many batches are run or units of product are produced and sold. Product-level activities
include tasks such as designing a product and making engineering design changes to a
product. Costs at the product-level depend on the number of products supported rather
than the number of batches run or the number of units of product produced and sold.
To illustrate the differences between traditional and activity-based absorption costing, we’ll use an example focused on Maxtar Industries, a manufacturer of high-quality
smoker/barbecue units. The company has two product lines—Premium and Standard. The
company has traditionally applied manufacturing overhead costs to these products using a
plantwide predetermined overhead rate based on direct labor-hours. Exhibit 3A–1 details
how the unit product costs of the two product lines are computed using the company’s

traditional costing system. The company’s activity-based approach simply provides an
alternative way to allocate the company’s manufacturing overhead across the two products.
The activity rates for the three activity cost pools are computed in the second table in
Exhibit 3A–2. For example, the total cost in the “setting up machines” activity cost pool,
$480,000, is divided by the total activity associated with that cost pool, 800 setups, to
determine the activity rate of $600 per setup.
The activity rates are used to allocate overhead costs to the two products in the third
table in Exhibit 3A–2. For example, the activity rate for the “setting up machines” activity cost pool, $600 per setup, is multiplied by the Premium product line’s 600 setups to
determine the $360,000 machine setup cost allocated to the Premium product line.
The table at the bottom of Exhibit 3A–2 displays the overhead costs per unit and the
activity-based unit product costs. The overhead cost per unit is determined by dividing the
total overhead cost by the number of units produced. For example, the Premium product
line’s total overhead cost of $728,000 is divided by 50,000 units to determine the $14.56
overhead cost per unit. Note that the unit product costs differ from those computed using the
company’s traditional costing system in Exhibit 3A–1. Because the activity-based approach
contains both a batch-level (setting up machines) and a product-level (parts administration)
activity cost pool, the unit product costs under the activity-based approach follow the usual
pattern in which overhead costs are shifted from the high-volume to the low-volume product. The unit product cost of the Standard product line, the high-volume product, has gone
down from $53.70 under the traditional costing system to $51.96 under activity-based costing. In contrast, the unit product cost of the Premium product line, the low-volume product,
has increased from $71.60 under the traditional costing system to $78.56 under activitybased costing. Instead of using direct labor-hours (which moves in tandem with the volume
of the production) to assign all manufacturing overhead costs to products, the activity-based
approach uses a batch-level activity measure and a product-level activity measure to assign
the batch-level and product-level activity cost pools to the two products.

Siegel Company manufactures a product that is available in both a deluxe model and a regular model. The company has manufactured the regular model for years. The deluxe model
was introduced several years ago to tap a new segment of the market. Since introduction of
the deluxe model, the company’s profits have steadily declined and management has become
increasingly concerned about the accuracy of its costing system. Sales of the deluxe model have
been increasing rapidly.
Manufacturing overhead is assigned to products on the basis of direct labor-hours. For the
current year, the company has estimated that it will incur $900,000 in manufacturing overhead cost
and produce 5,000 units of the deluxe model and 40,000 units of the regular model. The deluxe
model requires two hours of direct labor time per unit, and the regular model requires one hour.
Material and labor costs per unit are as follows:

Management is considering using activity-based absorption costing to apply manufacturing
overhead cost to products. The activity-based system would have the following four activity

Using the predetermined overhead rates you computed in part (2), do the following:
a. Compute the total amount of manufacturing overhead cost that would be applied to each
model using the activity-based absorption costing system. After these totals have been
computed, determine the amount of manufacturing overhead cost per unit of each model.
b. Compute the unit product cost of each model (direct materials, direct labor, and manufacturing overhead).
From the data you have developed in parts (1) through (3), identify factors that may account
for the company’s declining profits.
CASE 3A–6 Activity-Based Absorption Costing and Pricing [LO3–8]
Java Source, Inc. (JSI), is a processor and distributor of a variety of blends of coffee. The company buys coffee beans from around the world and roasts, blends, and packages them for resale.
JSI offers a large variety of different coffees that it sells to gourmet shops in one-pound bags. The
major cost of the coffee is raw materials. However, the company’s predominantly automated roasting, blending, and packing processes require a substantial amount of manufacturing overhead. The
company uses relatively little direct labor.
Some of JSI’s coffees are very popular and sell in large volumes, while a few of the newer
blends sell in very low volumes. JSI prices its coffees at manufacturing cost plus a markup of 25%,
with some adjustments made to keep the company’s prices competitive.
For the coming year, JSI’s budget includes estimated manufacturing overhead cost of
$2,200,000. JSI assigns manufacturing overhead to products on the basis of direct labor-hours.
The expected direct labor cost totals $600,000, which represents 50,000 hours of direct labor time.
Based on the sales budget and expected raw materials costs, the company will purchase and use
$5,000,000 of raw materials (mostly coffee beans) during the year.
The expected costs for direct materials and direct labor for one-pound bags of two of the company’s coffee products appear below.

Appendix 3B: The Predetermined Overhead Rate and Capacity
LO3–9
Understand the implications
of basing the predetermined
overhead rate on activity
at capacity rather than on
estimated activity for the
period.
Companies typically base their predetermined overhead rates on the estimated, or budgeted, amount of the allocation base for the upcoming period. This is the method that is
used in the chapter, but it is a practice that is often criticized based on the accounting for
fixed manufacturing overhead costs.1 As we shall see, the critics argue that, in general,
too much fixed manufacturing overhead cost is applied to products. To focus on this
issue, we will make two simplifying assumptions in this appendix: (1) we will consider
only fixed manufacturing overhead; and (2) we will assume that the actual fixed manufacturing overhead at the end of the period is the same as the estimated, or budgeted,
fixed manufacturing overhead at the beginning of the period. Neither of these assumptions is entirely realistic. Ordinarily, some manufacturing overhead is variable and even
fixed costs can differ from what was expected at the beginning of the period, but making
those assumptions enables us to focus on the primary issues the critics raise.
An example will help us to understand the controversy. Prahad Corporation manufactures music CDs for local recording studios. The company’s CD duplicating machine
is capable of producing a new CD every 10 seconds from a master CD. The company
leases the CD duplicating machine for $180,000 per year, and this is the company’s only
manufacturing overhead cost. With allowances for setups and maintenance, the machine
is theoretically capable of producing up to 900,000 CDs per year. However, due to weak
retail sales of CDs, the company’s commercial customers are unlikely to order more than
600,000 CDs next year. The company uses machine time as the allocation base for applying manufacturing overhead to CDs. These data are summarized below:

Statement of Financial Accounting Standards No. 151: Inventory Costs and International Accounting
Standard 2: Inventories require allocating fixed manufacturing overhead costs to products based on normal
capacity. Normal capacity reflects the level of output expected to be produced over numerous periods under
normal circumstances. This definition mirrors the language used in this book that refers to basing the predetermined overhead rate on the estimated, or budgeted, amount of the allocation base for the upcoming period.
Job-Order Costing
If Prahad follows common practice and computes its predetermined overhead rate
using estimated or budgeted figures, then its predetermined overhead rate for next year
would be $0.03 per second of machine time computed as follows:
Predetermined _____________________________________
Estimated total manufacturing overhead cost
overhead rate 5 Estimated total amount of the allocation base
$180,000
5 _____________________________
600,000 CDs 3 10 seconds per CD
5 $0.03 per second
Because each CD requires 10 seconds of machine time, each CD will be charged for
$0.30 of overhead cost.
Critics charge that there are two problems with this procedure. First, if predetermined overhead rates are based on budgeted activity and overhead includes significant
fixed costs, then the unit product costs will fluctuate depending on the budgeted level of
activity for the period. For example, if the budgeted output for the year was only 300,000
CDs, the predetermined overhead rate would be $0.06 per second of machine time or
$0.60 per CD rather than $0.30 per CD. In general, if budgeted output falls, the overhead
cost per unit will increase; it will appear that the CDs cost more to make. Managers may
then be tempted to increase prices at the worst possible time—just as demand is falling.
Second, critics charge that under the traditional approach, products are charged for
resources that they don’t use. When the fixed costs of capacity are spread over estimated
activity, the units that are produced must shoulder the costs of unused capacity. That is
why the applied overhead cost per unit increases as the level of activity falls. The critics
argue that products should be charged only for the capacity that they use; they should
not be charged for the capacity they don’t use. This can be accomplished by basing the
predetermined overhead rate on capacity as follows:
Estimated total manufacturing overhead cost at capacity
Predetermined overhead 5 ______________________________________________
rate based on capacity
Estimated total amount of the allocation base at capacity
$180,000
5 _____________________________
900,000 CDs 3 10 seconds per CD
5 $0.02 per second
It is important to realize that the numerator in this predetermined overhead rate is the
estimated total manufacturing overhead cost at capacity. In general, the numerator in
a predetermined overhead rate is the estimated total manufacturing overhead cost for
the level of activity in the denominator. Ordinarily, the estimated total manufacturing
overhead cost at capacity will be larger than the estimated total manufacturing overhead
cost at the estimated level of activity. The estimated level of activity in this case was
600,000 CDs (or 6 million seconds of machine time), whereas capacity is 900,000 CDs
(or 9 million seconds of machine time). The estimated total manufacturing overhead cost
at 600,000 CDs was $180,000. This also happens to be the estimated total manufacturing
overhead cost at 900,000 CDs, but that only happens because we have assumed that the
manufacturing overhead is entirely fixed. If manufacturing overhead contained any variable element, the total manufacturing overhead would be larger at 900,000 CDs than at
600,000 CDs and, in that case, the predetermined overhead rate should reflect that fact.
At any rate, returning to the computation of the predetermined overhead rate based
on capacity, the predetermined overhead rate is $0.02 per second and so the overhead cost
applied to each CD would be $0.20. This charge is constant and would not be affected by
the level of activity during a period. If output falls, the charge would still be $0.20 per CD.
This method will almost certainly result in underapplied overhead. If actual output
at Prahad Corporation is 600,000 CDs, then only $120,000 of overhead cost would be
applied to products ($0.20 per CD 3 600,000 CDs). Because the actual overhead cost is
$180,000, overhead would be underapplied by $60,000. Because we are assuming that
139
140
Chapter 3
manufacturing overhead is entirely fixed and that actual manufacturing overhead equals
the manufacturing overhead as estimated at the beginning of the year, the underapplied
overhead represents the cost of unused capacity. In other words, if there had been no
unused capacity, there would have been no underapplied overhead. The critics suggest
that the underapplied overhead that results from unused capacity should be separately
disclosed on the income statement as the Cost of Unused Capacity—a period expense.
Disclosing this cost as a lump sum of $60,000 on the income statement, rather than burying it in Cost of Goods Sold or ending inventories, makes it much more visible to managers. An example of such an income statement appears below:

Wixis Cabinets makes custom wooden cabinets for high-end stereo systems from specialty woods.
The company uses a job-order costing system. The capacity of the plant is determined by the
capacity of its constraint, which is time on the automated bandsaw that makes finely beveled cuts
in wood according to the preprogrammed specifications of each cabinet. The bandsaw can operate up to 180 hours per month. The estimated total manufacturing overhead at capacity is $14,760
per month. The company bases its predetermined overhead rate on capacity, so its predetermined
overhead rate is $82 per hour of bandsaw use.

CASE 3B–4 Ethics; Predetermined Overhead Rate and Capacity [LO3–2, LO3–7, LO3–9]
Pat Miranda, the new controller of Vault Hard Drives, Inc., has just returned from a seminar on
the choice of the activity level in the predetermined overhead rate. Even though the subject did not
sound exciting at first, she found that there were some important ideas presented that should get a
hearing at her company. After returning from the seminar, she arranged a meeting with the production manager, J. Stevens, and the assistant production manager, Marvin Washington.
Pat: I ran across an idea that I wanted to check out with both of you. It’s about the way we compute
predetermined overhead rates.
J.: We’re all ears.
Pat: We compute the predetermined overhead rate by dividing the estimated total factory overhead for
the coming year, which is all a fixed cost, by the estimated total units produced for the coming year.
Marvin: We’ve been doing that as long as I’ve been with the company.
J.: And it has been done that way at every other company I’ve worked at, except at most places they
divide by direct labor-hours.
Pat: We use units because it is simpler and we basically make one product with minor variations. But,
there’s another way to do it. Instead of basing the overhead rate on the estimated total units produced for the coming year, we could base it on the total units produced at capacity.
Marvin: Oh, the Marketing Department will love that. It will drop the costs on all of our products.
They’ll go wild over there cutting prices.
Pat: That is a worry, but I wanted to talk to both of you first before going over to Marketing.
J.: Aren’t you always going to have a lot of underapplied overhead?

budget for next year.

the income statement, someone from headquarters is likely to come down here looking for some
people to lay off.
Marvin: I’m worried about something else too. What happens when sales are not up to expectations?
Can we pull the “hat trick”?
Pat: I’m sorry, I don’t understand.
J.: Marvin’s talking about something that happens fairly regularly. When sales are down and profits
look like they are going to be lower than the president told the owners they were going to be, the
president comes down here and asks us to deliver some more profits.
Marvin: And we pull them out of our hat.
J.: Yeah, we just increase production until we get the profits we want.
Pat: I still don’t understand. You mean you increase sales?
J.: Nope, we increase production. We’re the production managers, not the sales managers.
Pat: I get it. Because you have produced more, the sales force has more units it can sell.
J.: Nope, the marketing people don’t do a thing. We just build inventories and that does the trick.
Required:
In all of the questions below, assume that the predetermined overhead rate under the traditional
method is $25 per unit, and under the new method it is $20 per unit. Also assume that under the
traditional method any underapplied or overapplied overhead is taken directly to the income statement as an adjustment to Cost of Goods Sold.
1. Suppose actual production is 160,000 units. Compute the net operating incomes that would
be realized under the traditional and new methods if actual sales are 150,000 units and everything else turns out as expected.
2. How many units would have to be produced under each of the methods in order to realize the
budgeted net operating income of $500,000 if actual sales are 150,000 units and everything
else turns out as expected?
3. What effect does the new method based on capacity have on the volatility of net operating
income?
4. Will the “hat trick” be easier or harder to perform if the new method based on capacity is used?
5. Do you think the “hat trick” is ethical?

Process Costing
Costing the “Quicker-Picker-Upper”
BUSIN ESS FO CUS
If you have ever spilled milk,
there is a good chance that
you used Bounty paper
towels to clean up the
mess. Procter & Gamble
(P&G) manufactures Bounty
in two main processing
departments—Paper Making and Paper Converting.
In the Paper Making Department, wood pulp is converted into paper and then
spooled into 2,000 pound
rolls. In the Paper Converting Department, two of the
2,000 pound rolls of paper
are simultaneously unwound
into a machine that creates
a two-ply paper towel that is
decorated, perforated, and
embossed to create texture.
The large sheets of paper
towels that emerge from
this process are wrapped
around a cylindrical cardboard core measuring eight feet in length. Once
enough sheets wrap around the core, the eight foot roll is cut into individual
rolls of Bounty that are sent down a conveyor to be wrapped, packed, and
shipped.
In this type of manufacturing environment, costs cannot be readily traced to
individual rolls of Bounty; however, given the homogeneous nature of the product, the total costs incurred in the Paper Making Department can be spread
uniformly across its output of 2,000 pound rolls of paper. Similarly, the total
costs incurred in the Paper Converting Department (including the cost of the
2,000 pound rolls that are transferred in from the Paper Making Department)
can be spread uniformly across the number of cases of Bounty produced.
P&G uses a similar costing approach for many of its products such as
Tide, Crest toothpaste, and Dawn dishwashing liquid. ■

Process Costing
ob-order costing and process costing are two common methods
for determining unit product costs. As explained in the previous chapter, job-order
costing is used when many different jobs or products are worked on each period.
Examples of industries that use job-order costing include furniture manufacturing,
special-order printing, shipbuilding, and many types of service organizations.
By contrast, process costing is used most commonly in industries that convert raw
materials into homogeneous (i.e., uniform) products, such as bricks, soda, or paper,
on a continuous basis. Examples of companies that would use process costing include
Reynolds Consumer Products (aluminum ingots), Scott Paper (paper towels), General
Mills (flour), ExxonMobil (gasoline and lubricating oils), Coppertone (sunscreens),
and Kellogg’s (breakfast cereals). In addition, process costing is sometimes used in companies with assembly operations. A form of process costing may also be used in utilities
that produce gas, water, and electricity.
Our purpose in this chapter is to explain how product costing works in a process costing system.
J
Comparison of Job-Order and Process Costing
In some ways process costing is very similar to job-order costing, and in some ways it is
very different. In this section, we focus on these similarities and differences to provide a
foundation for the detailed discussion of process costing that follows.
Similarities between Job-Order and Process Costing
Much of what you learned in the previous chapter about costing and cost flows applies
equally well to process costing in this chapter. We are not throwing out all that we have
learned about costing and starting from “scratch” with a whole new system. The similarities between job-order and process costing can be summarized as follows:
1. Both systems have the same basic purposes—to assign material, labor, and manufacturing overhead costs to products and to provide a mechanism for computing unit
product costs.
2. Both systems use the same basic manufacturing accounts, including Manufacturing
Overhead, Raw Materials, Work in Process, and Finished Goods.
3. The flow of costs through the manufacturing accounts is basically the same in both
systems.
As can be seen from this comparison, much of the knowledge that you have already
acquired about costing is applicable to a process costing system. Our task now is to refine
and extend your knowledge to process costing.
Differences between Job-Order and Process Costing
There are three differences between job-order and process costing. First, process
costing is used when a company produces a continuous flow of units that are indistinguishable from one another. Job-order costing is used when a company produces
many different jobs that have unique production requirements. Second, under process
costing, it makes no sense to try to identify materials, labor, and overhead costs with
a particular customer order (as we did with job-order costing) because each order is
just one of many that are filled from a continuous flow of virtually identical units
from the production line. Accordingly, process costing accumulates costs by department (rather than by order) and assigns these costs uniformly to all units that pass
through the department during a period. Job cost sheets (which we used for job-order
costing) are not used to accumulate costs. Third, process costing systems compute

computed by job on the job cost sheet. Exhibit 4–1 summarizes the differences just
described.
Cost Flows in Process Costing
Before going through a detailed example of process costing, it will be helpful to see how,
in a general way, manufacturing costs flow through a process costing system.
Processing Departments
A processing department is an organizational unit where work is performed on a product and where materials, labor, or overhead costs are added to the product. For example, a
Nalley’s potato chip factory might have three processing departments—one for preparing
potatoes, one for cooking, and one for inspecting and packaging. A brick factory might
have two processing departments—one for mixing and molding clay into brick form and
one for firing the molded brick. Some products and services may go through a number of
processing departments, while others may go through only one or two. Regardless of the
number of processing departments, they all have two essential features. First, the activity
in the processing department is performed uniformly on all of the units passing through
it. Second, the output of the processing department is homogeneous; in other words, all
of the units produced are identical.
Products in a process costing environment, such as bricks or potato chips, typically
flow in sequence from one department to another as in Exhibit 4–2.

IN BUSINESS
MONKS MAKE A LIVING SELLING BEER
The Trappist monks of St. Sixtus monastery in Belgium have been brewing beer since 1839. Customers must make an appointment with the monastery to buy a maximum of two 24-bottle cases
per month. The scarce and highly prized beer sells for more than $15 per 11-ounce bottle.
The monk’s brewing ingredients include water, malt, hops, sugar, and yeast. The sequential
steps of the beer-making process include grinding and crushing the malt grain, brewing by adding
water to the crushed malt, filtering to separate a liquid called wort from undissolved grain particles,
boiling to sterilize the wort (including adding sugar to increase the density of the wort), fermentation
by adding yeast to convert sugar into alcohol and carbon dioxide, storage where the beer is aged
for at least three weeks, and bottling where more sugar and yeast are added to enable two weeks
of additional fermentation in the bottle.
Unlike growth-oriented for-profit companies, the monastery has not expanded its production
capacity since 1946, seeking instead to sell just enough beer to sustain the monks’ modest lifestyle.

The Flow of Materials, Labor, and Overhead Costs
Cost accumulation is simpler in a process costing system than in a job-order costing system. In a process costing system, instead of having to trace costs to hundreds of different
jobs, costs are traced to only a few processing departments.
A T-account model of materials, labor, and overhead cost flows in a process costing
system is shown in Exhibit 4–3. Several key points should be noted from this exhibit. First,
note that a separate Work in Process account is maintained for each processing department.

Chapter 4
In contrast, in a job-order costing system the entire company may have only one Work in
Process account. Second, note that the completed production of the first processing department (Department A in the exhibit) is transferred to the Work in Process account of the
second processing department (Department B). After further work in Department B, the
completed units are then transferred to Finished Goods. (In Exhibit 4–3, we show only two
processing departments, but a company can have many processing departments.)
Finally, note that materials, labor, and overhead costs can be added in any processing department—not just the first. Costs in Department B’s Work in Process account
consist of the materials, labor, and overhead costs incurred in Department B plus the
costs attached to partially completed units transferred in from Department A (called
transferred-in costs).
Materials, Labor, and Overhead Cost Entries
LO4–1
Record the flow of materials,
labor, and overhead through a
process costing system.
To complete our discussion of cost flows in a process costing system, in this section we
show journal entries relating to materials, labor, and overhead costs at Megan’s Classic
Cream Soda, a company that has two processing departments—Formulating and Bottling.
In the Formulating Department, ingredients are checked for quality and then mixed and
injected with carbon dioxide to create bulk cream soda. In the Bottling Department,
bottles are checked for defects, filled with cream soda, capped, visually inspected again
for defects, and then packed for shipping.
Materials Costs As in job-order costing, materials are drawn from the storeroom
using a materials requisition form. Materials can be added in any processing department,
although it is not unusual for materials to be added only in the first processing department, with subsequent departments adding only labor and overhead costs.
At Megan’s Classic Cream Soda, some materials (i.e., water, flavors, sugar, and carbon dioxide) are added in the Formulating Department and some materials (i.e., bottles,
caps, and packing materials) are added in the Bottling Department. The journal entry to
record the materials used in the first processing department, the Formulating Department,
is as follows:

Bottling Department, is as follows:

Labor Costs In process costing, labor costs are traced to departments—not to
individual jobs. The following journal entry records the labor costs in the Formulating
Department at Megan’s Classic Cream Soda:

A similar entry would be made to record labor costs in the Bottling Department.
Overhead Costs In process costing, as in job-order costing, predetermined overhead rates are usually used. Manufacturing overhead cost is applied according to the
amount of the allocation base that is incurred in the department. The following journal
entry records the overhead cost applied in the Formulating Department:
Work in Process—Formulating . . . . . . . . . . . . . . . . . . . . . . . . . . . .

A similar entry would be made to apply manufacturing overhead costs in the Bottling

Completing the Cost Flows Once processing has been completed in a department, the units are transferred to the next department for further processing, as illustrated
in the T-accounts in Exhibit 4–3. The following journal entry transfers the cost of partially completed units from the Formulating Department to the Bottling Department:
Work in Process—Bottling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . XXX
Work in Process—Formulating . . . . . . . . . . . . . . . . . . . . . . . . . . .
XXX
After processing has been completed in the Bottling Department, the costs of the
completed units are transferred to the Finished Goods inventory account:
Finished Goods . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . XXX
XXX
Work in Process—Bottling . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Finally, when a customer’s order is filled and units are sold, the cost of the units is
transferred to Cost of Goods Sold:
Cost of Goods Sold . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . XXX
Finished Goods . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
XXX
To summarize, the cost flows between accounts are basically the same in a process
costing system as they are in a job-order costing system. The only difference at this point is
that in a process costing system each department has a separate Work in Process account.
THE DIFFERENCE BETWEEN LABOR RATES AND LABOR COST
IN BUSINESS
The emergence of China as a global competitor has increased the need for managers to understand the difference between labor rates and labor cost. Labor rates reflect the amount paid to
employees per hour or month. Labor costs measure the employee compensation paid per unit of
output. For example, Tenneco has plants in Shanghai, China, and Litchfield, Michigan, that both
manufacture exhaust systems for automobiles. The monthly labor rate per employee at the Shanghai plant ranges from $210–$250, whereas the same figure for the Litchfield plant ranges from
$1,880–$4,064. A naïve interpretation of these labor rates would be to automatically assume that
the Shanghai plant is the lower labor cost facility. A wiser comparison of the two plants’ labor costs
would account for the fact that the Litchfield plant produced 1.4 million exhaust systems in 2005
compared to 400,000 units at the Shanghai plant, while having only 20% more employees than the
Shanghai plant.

We now turn our attention to Double Diamond Skis, a company that manufactures a
high-performance deep-powder ski, and that uses process costing to determine its unit
product costs. The company’s production process is illustrated in Exhibit 4–4. Skis go
through a sequence of five processing departments, starting with the Shaping and Milling
Department and ending with the Finishing and Pairing Department. The basic idea in process costing is to add together all of the costs incurred in a department during a period and
then to spread those costs uniformly across the units processed in that department during
that period. As we shall see, applying this simple idea involves a few complications.
Equivalent Units of Production
After materials, labor, and overhead costs have been accumulated in a department, the
department’s output must be determined so that unit product costs can be computed. The
difficulty is that a department usually has some partially completed units in its ending

inventory. It does not seem reasonable to count these partially completed units as equivalent to fully completed units when counting the department’s output. Therefore, these
partially completed units are translated into an equivalent number of fully completed
units. In process costing, this translation is done using the following formula:
Equivalent units 5 Number of partially completed units 3 Percentage completion
As the formula states, equivalent units is the product of the number of partially completed units and the percentage completion of those units with respect to the processing in
the department. Roughly speaking, the equivalent units is the number of complete units
that could have been obtained from the materials and effort that went into the partially
complete units.
For example, suppose the Molding Department at Double Diamond has 500 units in
its ending work in process inventory that are 60% complete with respect to processing in
the department. These 500 partially complete units are equivalent to 300 fully complete
units (500 3 60% 5 300). Therefore, the ending work in process inventory contains
300 equivalent units. These equivalent units are added to any units completed during the
period to determine the department’s output for the period—called the equivalent units
of production.
Equivalent units of production for a period can be computed in different ways. In this
chapter, we discuss the weighted-average method. In Appendix 4A, we discuss the FIFO
method. The FIFO method of process costing is a method in which equivalent units and
unit costs relate only to work done during the current period. In contrast, the weightedaverage method blends together units and costs from the current period with units and
costs from the prior period. In the weighted-average method, the equivalent units of
production for a department are the number of units transferred to the next department
(or to finished goods) plus the equivalent units in the department’s ending work in process inventory.
Weighted-Average Method
Under the weighted-average method, a department’s equivalent units are computed as
follows:
Weighted-Average Method
(a separate calculation is made for each cost category in
each processing department)
Equivalent units
Equivalent units in ending
5 Units transferred to the next 1
of production
department or to finished goods work in process inventory
Note that the computation of the equivalent units of production involves adding the number of units transferred out of the department to the equivalent units in the department’s
ending inventory. There is no need to compute the equivalent units for the units transferred out of the department—they are 100% complete with respect to the work done in
that department or they would not be transferred out. In other words, each unit transferred
out of the department is counted as one equivalent unit.
Consider the Shaping and Milling Department at Double Diamond. This department
uses computerized milling machines to precisely shape the wooden core and metal sheets
that will be used to form the backbone of the ski. (See Exhibit 4–4 for an overview of the
production process at Double Diamond.) The activity shown at the top of the next page
took place in the department in May.
The first thing to note about the activity in the Shaping and Milling Department
is the flow of units through the department. The department started with 200 units in
beginning work in process inventory. During May, 5,000 units were started into production. This made a total of 5,200 units. Of this total, 4,800 units were completed and
transferred to the next department during May and 400 units were still in the department
at the end of the month as ending work in process inventory. In general, the units in

beginning work in process inventory plus the units started into production must equal
the units in ending work in process inventory plus the units completed and transferred
out. In equation form, this is:
Units in beginning work in process inventory 1 Units started into production
or transferred in 5 Units in ending work in process inventory 1 Units completed
and transferred out
Note the use of the term conversion in the table above. Conversion cost, as defined
in an earlier chapter, is direct labor cost plus manufacturing overhead cost. In process
costing, conversion cost is often treated as a single element of product cost.
Note that the beginning work in process inventory was 55% complete with respect
to materials costs and 30% complete with respect to conversion costs. This means that
55% of the materials costs required to complete the units in the department had already
been incurred. Likewise, 30% of the conversion costs required to complete the units had
already been incurred.
Two equivalent unit figures must be computed—one for materials and one for conversion. These computations are shown in Exhibit 4–5.
Note that the computations in Exhibit 4–5 ignore the fact that the units in the beginning work in process inventory were partially complete. For example, the 200 units in
beginning inventory were already 30% complete with respect to conversion costs. Nevertheless, the weighted-average method is concerned only with the 4,900 equivalent units
that are in ending inventories and in units transferred to the next department; it is not
concerned with the fact that the beginning inventory was already partially complete. In
other words, the 4,900 equivalent units computed using the weighted-average method
include work that was accomplished in prior periods. This is a key point concerning the
weighted-average method and it is easy to overlook.

GETTING LESS FOR THE SAME PRICE
When the prices of raw materials such as sugar and cotton increase during an economic downturn,
companies realize that they cannot pass these cost increases on to customers in the form of higher
prices. Instead, companies often respond to these circumstances by holding their prices constant
while giving customers less for their money. For example, when the price of cotton increased
Georgia-Pacific responded by decreasing the width of its Angel Soft Double Roll toilet paper from
4.27 inches to 4.00 inches. The company also reduced the number of sheets per roll from 352 to
300. Similarly, Procter & Gamble decreased the number of sheets in a roll of Charmin Ultra Soft Big
Roll from 200 to 176.
These product size reductions not only lower raw material costs, but they also reduce shipping
costs. Georgia-Pacific estimates that its smaller rolls of toilet paper enable it to transport 12–17%
more units per truck, thereby saving 345,000 gallons of gasoline per year.

Cost per Equivalent Unit—Weighted-Average Method
In the weighted-average method, the cost per equivalent unit is computed as follows:
Weighted-Average Method
(a separate calculation is made for each cost category in each processing department)
Cost added
Cost of beginning
1
during
the period
work in process inventory
Cost per equivalent unit 5 ______________________________________
Equivalent units of production
Note that the numerator is the sum of the cost of beginning work in process inventory and
of the cost added during the period. Thus, the weighted-average method blends together
costs from the prior and current periods. That is why it is called the weighted-average
method; it averages together units and costs from both the prior and current periods.
The costs per equivalent unit for materials and for conversion are computed below
for the Shaping and Milling Department for May:

Applying Costs—Weighted-Average Method
LO4–4
Assign costs to units using the
weighted-average method.
The costs per equivalent unit are used to value units in ending inventory and units
that are transferred to the next department. For example, each unit transferred out of
Double Diamond’s Shaping and Milling Department to the Graphics Application
Department, as depicted in Exhibit 4–4, will carry with it a cost of $149.00 ($76.25 for
Process Costing
155
materials cost and $72.75 for conversion cost). Because 4,800 units were transferred out
in May to the next department, the total cost assigned to those units would be $715,200
(5 4,800 units 3 $149.00 per unit).
A complete accounting of the costs of both ending work in process inventory and the
units transferred out appears below:

In each case, the equivalent units are multiplied by the cost per equivalent unit to determine the cost assigned to the units. This is done for each cost category—in this case,
materials and conversion. The equivalent units for the units completed and transferred out
are simply the number of units transferred to the next department because they would not
have been transferred unless they were complete.

The costs assigned to ending work in process inventory and to the units transferred out

The $715,200 cost of the units transferred to the next department, Graphics Application, will be accounted for in that department as “costs transferred in.” It will be treated in
the process costing system as just another category of costs like materials or conversion
costs. The only difference is that the costs transferred in will always be 100% complete
with respect to the work done in the Graphics Applications Department. Costs are passed
on from one department to the next in this fashion, until they reach the last processing
department, Finishing and Pairing. When the products are completed in this last department, their costs are transferred to finished goods.

Chapter 4
Operation Costing
The costing systems discussed in Chapters 3 and 4 represent the two ends of a continuum.
On one end is job-order costing, which is used by companies that produce many different
products in one facility. On the other end is process costing, which is used by companies that produce homogeneous products in large quantities. Between these two extremes
there are many hybrid systems that include characteristics of both job-order and process
costing. One of these hybrids is called operation costing.
Operation costing is used in situations where products have some common characteristics and some individual characteristics. Shoes, for example, have common characteristics in that all styles involve cutting and sewing that can be done on a repetitive basis,
using the same equipment and following the same basic procedures. Shoes also have
individual characteristics—some are made of expensive leathers and others may be made
using inexpensive synthetic materials. In a situation such as this, where products have
some common characteristics but also must be processed individually, operation costing
may be used to determine product costs.
As mentioned above, operation costing is a hybrid system that employs aspects of
both job-order and process costing. Products are typically processed in batches when
operation costing is used, with each batch charged for its own specific materials. In this
sense, operation costing is similar to job-order costing. However, labor and overhead costs
are accumulated by operation or by department, and these costs are assigned to units as in
process costing. If shoes are being produced, each shoe is charged the same per unit conversion cost, regardless of the style involved, but it is charged with its specific materials
cost. Thus, the company is able to distinguish between styles in terms of materials, but it
is able to employ the simplicity of a process costing system for labor and overhead costs.
Examples of other products for which operation costing may be used include electronic
equipment (such as semiconductors), textiles, clothing, and jewelry (such as rings, bracelets,
and medallions). Products of this type are typically produced in batches, but they can vary
considerably from model to model or from style to style in terms of the cost of materials.
Summary
Process costing is used in situations where homogeneous products or services are produced on a
continuous basis. Costs flow through the manufacturing accounts in basically the same way in a
process costing system as in a job-order costing system. However, costs are accumulated by department rather than by job in process costing.
In process costing, the equivalent units of production must be determined for each cost category in each department. Under the weighted-average method, the equivalent units of production equals the number of units transferred out to the next department or to finished goods plus
the equivalent units in ending work in process inventory. The equivalent units in ending inventory
equals the product of the number of partially completed units in ending work in process inventory
and their percentage of completion with respect to the specific cost category.
Under the weighted-average method, the cost per equivalent unit for a specific cost category is
computed by adding the cost of beginning work in process inventory and the cost added during the
period and then dividing the result by the equivalent units of production. The cost per equivalent
unit is then used to value the ending work in process inventory and the units transferred out to the
next department or to finished goods.
The cost reconciliation report reconciles the cost of beginning inventory and the costs added
to production during the period to the cost of ending inventory and the cost of units transferred out.
Costs are transferred from one department to the next until the last processing department. At
that point, the cost of completed units is transferred to finished goods.

“He’s struggling to learn our system,” replied Frank Harrop, the operations manager. “The
problem is that he’s been away from process costing for a long time, and it’s coming back slowly.”
“It’s not just the format of his report that I’m concerned about. Look at that $25.71 unit cost
that he’s come up with for April. Doesn’t that seem high to you?” said Ms. Scarpino.
“Yes, it does seem high; but on the other hand, I know we had an increase in materials prices
during April, and that may be the explanation,” replied Mr. Harrop. “I’ll get someone else to redo
this report and then we may be able to see what’s going on.”

CASE 4–20 Ethics and the Manager, Understanding the Impact of Percentage Completion on
Profit—Weighted-Average Method [LO4–2, LO4–3, LO4–4]
Gary Stevens and Mary James are production managers in the Consumer Electronics Division of
General Electronics Company, which has several dozen plants scattered in locations throughout
the world. Mary manages the plant located in Des Moines, Iowa, while Gary manages the plant in
El Segundo, California. Production managers are paid a salary and get an additional bonus equal
to 5% of their base salary if the entire division meets or exceeds its target profits for the year. The
bonus is determined in March after the company’s annual report has been prepared and issued to
stockholders.
Shortly after the beginning of the new year, Mary received a phone call from Gary that went
like this:
Gary: How’s it going, Mary?
Mary: Fine, Gary. How’s it going with you?

Gary: Great! I just got the preliminary profit figures for the division for last year and we are within
$200,000 of making the year’s target profits. All we have to do is pull a few strings, and we’ll be
over the top!
Mary: What do you mean?
Gary: Well, one thing that would be easy to change is your estimate of the percentage completion of
your ending work in process inventories.
Mary: I don’t know if I can do that, Gary. Those percentage completion figures are supplied by Tom
Winthrop, my lead supervisor, who I have always trusted to provide us with good estimates.
Besides, I have already sent the percentage completion figures to corporate headquarters.
Gary: You can always tell them there was a mistake. Think about it, Mary. All of us managers are doing
as much as we can to pull this bonus out of the hat. You may not want the bonus check, but the rest
of us sure could use it.
The final processing department in Mary’s production facility began the year with no work
in process inventories. During the year, 210,000 units were transferred in from the prior processing department and 200,000 units were completed and sold. Costs transferred in from the prior
department totaled $39,375,000. No materials are added in the final processing department. A
total of $20,807,500 of conversion cost was incurred in the final processing department during
the year.

Tom Winthrop estimated that the units in ending inventory in the final processing department
were 30% complete with respect to the conversion costs of the final processing department. If
this estimate of the percentage completion is used, what would be the Cost of Goods Sold for
the year?
Does Gary Stevens want the estimated percentage completion to be increased or decreased?
Explain why.
What percentage completion would result in increasing reported net operating income by
$200,000 over the net operating income that would be reported if the 30% figure were used?
Do you think Mary James should go along with the request to alter estimates of the percentage
completion? Why or why not?
Appendix 4A: FIFO Method
The FIFO method of process costing differs from the weighted-average method in two
ways: (1) the computation of equivalent units, and (2) the way in which costs of beginning inventory are treated. The FIFO method is generally considered more accurate than
the weighted-average method, but it is more complex. The complexity is not a problem
for computers, but the FIFO method is a little more difficult to understand and to learn
than the weighted-average method.
Equivalent Units—FIFO Method
The computation of equivalent units under the FIFO method differs from the computation
under the weighted-average method in two ways.
First, the “units transferred out” is divided into two parts. One part consists of the
units from the beginning inventory that were completed and transferred out, and the other
part consists of the units that were both started and completed during the current period.
Second, full consideration is given to the amount of work expended during the current period on units in the beginning work in process inventory as well as on units in the
ending inventory. Thus, under the FIFO method, both beginning and ending inventories
are converted to an equivalent units basis. For the beginning inventory, the equivalent
units represent the work done to complete the units; for the ending inventory, the equivalent units represent the work done to bring the units to a stage of partial completion at the
end of the period (the same as with the weighted-average method).
LO4–6
Compute the equivalent units
of production using the FIFO
method.

Chapter 4
The formula for computing the equivalent units of production under the FIFO method
is more complex than under the weighted-average method:
FIFO Method
(a separate calculation is made for each cost category
in each processing department)
Equivalent units of production 5 Equivalent units to complete beginning work in process
inventory*
1 Units started and completed during the period
1 Equivalent units in ending work in process inventory
(
*Equivalent units to
Units in beginning
Percentage completion
complete beginning work 5 work in process 3 100% 2 of beginning work in

inventory
process inventory
)
Or, the equivalent units of production can also be determined as follows:
Equivalent units of production 5 Units transferred out
1 Equivalent units in ending work in process
inventory
2 Equivalent units in beginning work in process
inventory
To illustrate the FIFO method, refer again to the data for the Shaping and Milling Department at Double Diamond Skis. The department completed and transferred
4,800 units to the Graphics Application Department during May. Because 200 of these
units came from the beginning inventory, the Shaping and Milling Department must
have started and completed 4,600 units during May. The 200 units in the beginning
inventory were 55% complete with respect to materials and only 30% complete with
respect to conversion costs when the month started. Thus, to complete these units the
department must have added another 45% of materials costs (100% 2 55% 5 45%) and
another 70% of conversion costs (100% 2 30% 5 70%). Following this line of reasoning, the equivalent units for the department for May would be computed as shown in
Exhibit 4A–1.

Comparison of Equivalent Units of Production under the
Weighted-Average and FIFO Methods
Stop at this point and compare the data in Exhibit 4A–1 with the data in Exhibit 4–5 in
the chapter, which shows the computation of equivalent units under the weighted-average
method. Also refer to Exhibit 4A–2, which compares the two methods.
The essential difference between the two methods is that the weighted-average
method blends work and costs from the prior period with work and costs in the current
period, whereas the FIFO method separates the two periods. To see this more clearly,
consider the following reconciliation of the two calculations of equivalent units:

Chapter 4
As shown in the reconciliation of the two costing methods, it is evident that the FIFO
method removes the equivalent units that were already in beginning inventory from the
equivalent units as defined using the weighted-average method. Thus, the FIFO method
isolates the equivalent units that are due to work performed during the current period.
The weighted-average method blends together the equivalent units already in beginning
inventory with the equivalent units that are due to work performed in the current period.
Cost per Equivalent Unit—FIFO Method
LO4–7
Compute the cost per
equivalent unit using the FIFO
method.
In the FIFO method, the cost per equivalent unit is computed as follows:

Equivalent units of production
Unlike the weighted-average method, in the FIFO method the cost per equivalent unit is
based only on the costs incurred in the department in the current period.
The costs per equivalent unit for materials and for conversion are computed below
for the Shaping and Milling Department for May:

Applying Costs—FIFO Method
LO4–8
Assign costs to units using the
FIFO method.
The costs per equivalent unit are used to value units in ending inventory and units that are
transferred to the next department. For example, each unit transferred out of the Shaping
and Milling Department to the Graphics Application Department will carry with it a cost
of $148.50—$76.00 for materials cost and $72.50 for conversion cost. Because 4,800
units were transferred out in May to the next department, the total cost assigned to those
units would be $712,800 (4,800 units 3 $148.50 per unit).
A complete accounting of the costs of both ending work in process inventory and the
units transferred out appears on the next page. It is more complicated than the weightedaverage method. This is because the cost of the units transferred out consists of three
separate components: (1) the cost of beginning work in process inventory; (2) the cost
to complete the units in beginning work in process inventory; and (3) the cost of units
started and completed during the period.
Again, note that the cost of the units transferred out consists of three distinct
components—the cost of beginning work in process inventory, the cost to complete
the units in beginning inventory, and the cost of units started and completed during the period. This is a major difference between the weighted-average and FIFO
methods.

The $715,265 cost of the units transferred to the next department, Graphics Application, will be accounted for in that department as “costs transferred in.” As in the weightedaverage method, this cost will be treated in the process costing system as just another
category of costs, like materials or conversion costs. The only difference is that the costs
transferred in will always be 100% complete with respect to the work done in the Graphics Applications Department. Costs are passed on from one department to the next in this
fashion, until they reach the last processing department, Finishing and Pairing. When the
products are completed in this last department, their costs are transferred to finished goods.

Chapter 4
A Comparison of Costing Methods
In most situations, the weighted-average and FIFO methods will produce very similar unit
costs. If there never are any ending inventories, the two methods will produce identical
results. The reason for this is that without any ending inventories, no costs can be carried
forward into the next period and the weighted-average method will base unit costs on just
the current period’s costs—just as in the FIFO method. If there are ending inventories, either
erratic input prices or erratic production levels would also be required to generate much of
a difference in unit costs under the two methods. This is because the weighted-average
method will blend the unit costs from the prior period with the unit costs of the current
period. Unless these unit costs differ greatly, the blending will not make much difference.
Nevertheless, from the standpoint of cost control, the FIFO method is superior to
the weighted-average method. Current performance should be evaluated based on costs
of the current period only but the weighted-average method mixes costs of the current
period with costs of the prior period. Thus, under the weighted-average method, the manager’s apparent performance in the current period is influenced by what happened in
the prior period. This problem does not arise under the FIFO method because the FIFO
method makes a clear distinction between costs of prior periods and costs incurred during
the current period. For the same reason, the FIFO method also provides more up-to-date
cost data for decision-making purposes.
On the other hand, the weighted-average method is simpler to apply than the FIFO
method, but computers can handle the additional calculations with ease once they have
been appropriately programmed.

In contrast, service departments do not directly engage in operating activities. Instead,
they provide services or assistance to the operating departments. Examples of operating departments include the Surgery Department at Mt. Sinai Hospital, the Geography
Department at the University of Washington, the Marketing Department at Allstate
Insurance Company, and production departments at manufacturers such as Mitsubishi,
Hewlett-Packard, and Michelin. In process costing, the processing departments are
all operating departments. Examples of service departments include Cafeteria, Internal
Auditing, Human Resources, Cost Accounting, and Purchasing.
The overhead costs of operating departments commonly include allocations of costs
from the service departments. To the extent that service department costs are classified
as production costs, they should be included in unit product costs and thus, must be allocated to operating departments in a process costing system.
Three approaches are used to allocate the costs of service departments to other
departments: the direct method, the step-down method, and the reciprocal method. These
three methods are discussed in the following sections. However, before getting into the
details of these methods, we will discuss interdepartmental services.
Interdepartmental Services Many service departments provide services to
each other, as well as to operating departments. For example, the Cafeteria Department
provides meals for all employees, including those assigned to other service departments, as well as to employees of the operating departments. In turn, the Cafeteria
Department may receive services from other service departments, such as from
Custodial Services or from Personnel. Services provided between service departments
are known as interdepartmental or reciprocal services.

Chapter 4
Direct Method
LO4–10
Allocate service department
costs to operating departments
using the direct method.
The direct method is the simplest of the three cost allocation methods. It ignores the
services provided by a service department to other service departments (e.g., interdepartmental services) and allocates all service department costs directly to operating
departments. Even if a service department (such as Personnel) provides a large amount
of service to another service department (such as the cafeteria), no allocations are made
between the two departments. Rather, all costs are allocated directly to the operating
departments, bypassing the other service departments; hence, the term direct method.
For an example of the direct method, consider Mountain View Hospital, which has
two service departments and two operating departments as shown below. The hospital
allocates its Hospital Administration costs on the basis of employee-hours and its
Custodial Services costs on the basis of square feet occupied.

The direct method of allocating the hospital’s service department costs to the operating
departments is shown in Exhibit 4B–1. Several things should be noted in this exhibit. First,
the employee-hours of the Hospital Administration Department and the Custodial Services
Department are ignored when allocating the costs of Hospital Administration using the
direct method. Under the direct method, any of the allocation base attributable to the service departments themselves is ignored; only the amount of the allocation base attributable
to the operating departments is used in the allocation. Note that the same rule is used when
allocating the costs of the Custodial Services Department. Even though the Hospital Administration and Custodial Services departments occupy some space, this is ignored when the
Custodial Services costs are allocated. Finally, note that after all allocations have been completed, all of the service department costs are contained in the two operating departments.

Although the direct method is simple, it is less accurate than the other methods
because it ignores interdepartmental services.
Step-Down Method
LO4–11
Unlike the direct method, the step-down method provides for allocation of a service
department’s costs to other service departments, as well as to operating departments.
The step-down method is sequential. The sequence typically begins with the department
that provides the greatest amount of service to other service departments. After its costs
have been allocated, the process continues, step by step, ending with the department that
provides the least amount of services to other service departments. This step procedure is
illustrated in Exhibit 4B–2.
Exhibit 4B–3 shows the details of the step-down method. Note the following three
key points about these allocations. First, under Allocation in Exhibit 4B–3, you see two
allocations, or steps. In the first step, the costs of Hospital Administration are allocated

to another service department (Custodial Services) as well as to the operating departments. In contrast to the direct method, the allocation base for Hospital Administration
costs now includes the employee-hours for Custodial Services as well as for the operating departments. However, the allocation base still excludes the employee-hours for
Hospital Administration itself. In both the direct and step-down methods, any amount
of the allocation base attributable to the service department whose cost is being allocated is always ignored. Second, looking again at Exhibit 4B–3, note that in the second
step under the Allocation heading, the cost of Custodial Services is allocated to the two
operating departments, and none of the cost is allocated to Hospital Administration even
though Hospital Administration occupies space in the building. In the step-down method,
any amount of the allocation base that is attributable to a service department whose cost
has already been allocated is ignored. After a service department’s costs have been allocated, costs of other service departments are not reallocated back to it. Third, note that the
cost of Custodial Services allocated to other departments in the second step ($130,000) in
Exhibit 4B–3 includes the costs of Hospital Administration that were allocated to Custodial Services in the first step in Exhibit 4B–3.
Reciprocal Method
The reciprocal method gives full recognition to interdepartmental services. Under the
step-down method only partial recognition of interdepartmental services is possible.
The step-down method always allocates costs forward—never backward. The reciprocal
method, by contrast, allocates service department costs in both directions. Thus, because
Custodial Services in the prior example provides services for Hospital Administration,
part of Custodial Services’ costs will be allocated back to Hospital Administration if
the reciprocal method is used. At the same time, part of Hospital Administration’s costs
will be allocated forward to Custodial Services. Reciprocal allocation requires the use
of simultaneous linear equations and is beyond the scope of this book. Examples of the
reciprocal method can be found in more advanced cost accounting texts.

CASE 4B–7 Step-Down Method versus Direct Method [LO4–10, LO4–11]
“This is really an odd situation,” said Jim Carter, general manager of Highland Publishing Company. “We get most of the jobs we bid on that require a lot of press time in the Printing Department,
yet profits on those jobs are never as high as they ought to be. On the other hand, we lose most of
the jobs we bid on that require a lot of time in the Binding Department. I would be inclined to think
that the problem is with our overhead rates, but we’re already computing separate overhead rates
for each department. So what else could be wrong?”
Highland Publishing Company is a large organization that offers a variety of printing and
binding work. The Printing and Binding departments are supported by three service departments.
The costs of these service departments are allocated to other departments in the order listed below.

Cost-Volume-Profit Relationships
Moreno Turns Around the Los Angeles Angels
BUSIN ESS FO CUS
LEARNING OBJECTIVES
After studying Chapter 5, you should be
able to:
LO5–1
Explain how changes in activity affect
contribution margin and net operating
income.
LO5–2
Prepare and interpret a cost-volumeprofit (CVP) graph and a profit graph.
LO5–3
Use the contribution margin ratio (CM
ratio) to compute changes in contribution
margin and net operating income
resulting from changes in sales volume.
When Arturo Moreno bought Major League Baseball’s Los Angeles Angels
in 2003, the team was drawing 2.3 million fans and losing $5.5 million per
year. Moreno immediately cut prices to attract more fans and increase profits. In his first spring training game, he reduced the price of selected tickets
from $12 to $6. By increasing attendance, Moreno understood that he would
sell more food and souvenirs. He dropped the price of draft beer by $2 and
cut the price of baseball caps from $20 to $7.
The Angels now consistently draw about 3.4 million fans per year.
This growth in attendance helped double stadium sponsorship revenue to
$26 million, and it motivated the Fox Sports Network to pay the Angels
$500 million to broadcast all of its games for the next ten years. Since
Moreno bought the Angels, annual revenues have jumped from $127 million
to $212 million, and the team’s operating loss of $5.5 million has been transformed to a profit of $10.3 million. ■

Chapter 5
ost-volume-profit (CVP) analysis helps managers make many
C
important decisions such as what products and services to offer, what prices to
charge, what marketing strategy to use, and what cost structure to maintain. Its primary purpose is to estimate how profits are affected by the following five factors:
1.
2.
3.
4.
5.
Selling prices.
Sales volume.
Unit variable costs.
Total fixed costs.
Mix of products sold.
To simplify CVP calculations, managers typically adopt the following assumptions
with respect to these factors1:
1. Selling price is constant. The price of a product or service will not change as volume
changes.
2. Costs are linear and can be accurately divided into variable and fixed elements. The
variable element is constant per unit. The fixed element is constant in total over the
entire relevant range.
3. In multiproduct companies, the mix of products sold remains constant.
While these assumptions may be violated in practice, the results of CVP analysis
are often “good enough” to be quite useful. Perhaps the greatest danger lies in relying on
simple CVP analysis when a manager is contemplating a large change in sales volume
that lies outside the relevant range. However, even in these situations the CVP model can
be adjusted to take into account anticipated changes in selling prices, variable costs per
unit, total fixed costs, and the sales mix that arise when the estimated sales volume falls
outside the relevant range.
To help explain the role of CVP analysis in business decisions, we’ll now turn our
attention to the case of Acoustic Concepts, Inc., a company founded by Prem Narayan.
MANAGERIAL
ACCOUNTING IN ACTION
THE ISSUE
Prem, who was a graduate student in engineering at the time, started Acoustic Concepts
to market a radical new speaker he had designed for automobile sound systems. The
speaker, called the Sonic Blaster, uses an advanced microprocessor and proprietary software to boost amplification to awesome levels. Prem contracted with a Taiwanese electronics manufacturer to produce the speaker. With seed money provided by his family,
Prem placed an order with the manufacturer and ran advertisements in auto magazines.
The Sonic Blaster was an immediate success, and sales grew to the point that Prem
moved the company’s headquarters out of his apartment and into rented quarters in a
nearby industrial park. He also hired a receptionist, an accountant, a sales manager, and
a small sales staff to sell the speakers to retail stores. The accountant, Bob Luchinni,
had worked for several small companies where he had acted as a business advisor as
well as accountant and bookkeeper. The following discussion occurred soon after Bob
was hired:
Prem: Bob, I’ve got a lot of questions about the company’s finances that I hope you can
help answer.
Bob: We’re in great shape. The loan from your family will be paid off within a few
months.
Prem: I know, but I am worried about the risks I’ve taken on by expanding operations.
What would happen if a competitor entered the market and our sales slipped? How
far could sales drop without putting us into the red? Another question I’ve been trying to resolve is how much our sales would have to increase to justify the big marketing campaign the sales staff is pushing for.
Bob: Marketing always wants more money for advertising.

One additional assumption often used in manufacturing companies is that inventories do not change.
The number of units produced equals the number of units sold.

Prem: And they are always pushing me to drop the selling price on the speaker. I
agree with them that a lower price will boost our sales volume, but I’m not sure the
increased volume will offset the loss in revenue from the lower price.
Bob: It sounds like these questions are all related in some way to the relationships
among our selling prices, our costs, and our volume. I shouldn’t have a problem coming up with some answers.
Prem: Can we meet again in a couple of days to see what you have come up with?
Bob: Sounds good. By then I’ll have some preliminary answers for you as well as a
model you can use for answering similar questions in the future.
The Basics of Cost-Volume-Profit (CVP) Analysis
Bob Luchinni’s preparation for his forthcoming meeting with Prem begins with the contribution income statement. The contribution income statement emphasizes the behavior
of costs and therefore is extremely helpful to managers in judging the impact on profits
of changes in selling price, cost, or volume. Bob will base his analysis on the following
contribution income statement he prepared last month:

Notice that sales, variable expenses, and contribution margin are expressed on a per
unit basis as well as in total on this contribution income statement. The per unit figures
will be very helpful to Bob in some of his calculations. Note that this contribution income
statement has been prepared for management’s use inside the company and would not
ordinarily be made available to those outside the company.
Contribution Margin
Contribution margin is the amount remaining from sales revenue after variable expenses
have been deducted. Thus, it is the amount available to cover fixed expenses and then to
provide profits for the period. Notice the sequence here—contribution margin is used first
to cover the fixed expenses, and then whatever remains goes toward profits. If the contribution margin is not sufficient to cover the fixed expenses, then a loss occurs for the period. To
illustrate with an extreme example, assume that Acoustic Concepts sells only one speaker
during a particular month. The company’s income statement would appear as follows:

Chapter 5
For each additional speaker the company sells during the month, $100 more in contribution margin becomes available to help cover the fixed expenses. If a second speaker
is sold, for example, then the total contribution margin will increase by $100 (to a total of
$200) and the company’s loss will decrease by $100, to $34,800:

If enough speakers can be sold to generate $35,000 in contribution margin, then all of
the fixed expenses will be covered and the company will break even for the month—that
is, it will show neither profit nor loss but just cover all of its costs. To reach the breakeven point, the company will have to sell 350 speakers in a month because each speaker
sold yields $100 in contribution margin:

Computation of the break-even point is discussed in detail later in the chapter; for
the moment, note that the break-even point is the level of sales at which profit is zero.
Once the break-even point has been reached, net operating income will increase by
the amount of the unit contribution margin for each additional unit sold. For example,
if 351 speakers are sold in a month, then the net operating income for the month will be
$100 because the company will have sold 1 speaker more than the number needed to
break even:

If 352 speakers are sold (2 speakers above the break-even point), the net operating income for the month will be $200. If 353 speakers are sold (3 speakers above the
break-even point), the net operating income for the month will be $300, and so forth. To
estimate the profit at any sales volume above the break-even point, multiply the number
of units sold in excess of the break-even point by the unit contribution margin. The result
Cost-Volume-Profit Relationships
represents the anticipated profits for the period. Or, to estimate the effect of a planned
increase in sales on profits, simply multiply the increase in units sold by the unit contribution margin. The result will be the expected increase in profits. To illustrate, if Acoustic
Concepts is currently selling 400 speakers per month and plans to increase sales to 425
speakers per month, the anticipated impact on profits can be computed as follows:

To summarize, if sales are zero, the company’s loss would equal its fixed expenses.
Each unit that is sold reduces the loss by the amount of the unit contribution margin.
Once the break-even point has been reached, each additional unit sold increases the company’s profit by the amount of the unit contribution margin.
CVP Relationships in Equation Form
The contribution format income statement can be expressed in equation form as follows:
Profit 5 (Sales 2 Variable expenses) 2 Fixed expenses
For brevity, we use the term profit to stand for net operating income in equations.
When a company has only a single product, as at Acoustic Concepts, we can further
refine the equation as follows:
Sales 5 Selling price per unit 3 Quantity sold 5 P 3 Q
Variable expenses 5 Variable expenses per unit 3 Quantity sold 5 V 3 Q
Profit 5 (P 3 Q 2 V 3 Q) 2 Fixed expenses
We can do all of the calculations of the previous section using this simple equation.
For example, on the previous page we computed that the net operating income (profit)
at sales of 351 speakers would be $100. We can arrive at the same conclusion using the
above equation as follows:
Profit 5 (P 3 Q 2 V 3 Q) 2 Fixed expenses
Profit 5 ($250 3 351 2 $150 3 351) 2 $35,000
5 ($250 2 $150) 3 351 2 $35,000
5 ($100) 3 351 2 $35,000
5 $35,100 2 $35,000 5 $100
191
192
Chapter 5
It is often useful to express the simple profit equation in terms of the unit contribution margin (Unit CM) as follows:
Unit CM 5 Selling price per unit 2 Variable expenses per unit 5 P 2 V
Profit 5 (P 3 Q 2 V 3 Q) 2 Fixed expenses
Profit 5 (P 2 V) 3 Q 2 Fixed expenses
Profit 5 Unit CM 3 Q 2 Fixed expenses
We could also have used this equation to determine the profit at sales of 351 speakers as
follows:
Profit 5 Unit CM 3 Q 2 Fixed expenses
5 $100 3 351 2 $35,000
5 $35,100 2 $35,000 5 $100
For those who are comfortable with algebra, the quickest and easiest approach to
solving the problems in this chapter may be to use the simple profit equation in one of
its forms.
CVP Relationships in Graphic Form
LO5–2
Prepare and interpret a costvolume-profit (CVP) graph and a
profit graph.
The relationships among revenue, cost, profit, and volume are illustrated on a costvolume-profit (CVP) graph. A CVP graph highlights CVP relationships over wide
ranges of activity. To help explain his analysis to Prem Narayan, Bob Luchinni prepared
a CVP graph for Acoustic Concepts.
Preparing the CVP Graph In a CVP graph (sometimes called a break-even
chart), unit volume is represented on the horizontal (X) axis and dollars on the vertical
(Y) axis. Preparing a CVP graph involves the three steps depicted in Exhibit 5–1:
1. Draw a line parallel to the volume axis to represent total fixed expense. For Acoustic
Concepts, total fixed expenses are $35,000.
2. Choose some volume of unit sales and plot the point representing total expense (fixed
and variable) at the sales volume you have selected. In Exhibit 5–1, Bob Luchinni
chose a volume of 600 speakers. Total expense at that sales volume is:
Fixed expense . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Variable expense (600 speakers 3 $150 per speaker) . . . . . . . . .

$ 35,000
90,000
$125,000
After the point has been plotted, draw a line through it back to the point where the
fixed expense line intersects the dollars axis.
3. Again choose some sales volume and plot the point representing total sales dollars
at the activity level you have selected. In Exhibit 5–1, Bob Luchinni again chose a
volume of 600 speakers. Sales at that volume total $150,000 (600 speakers 3 $250
per speaker). Draw a line through this point back to the origin.
The interpretation of the completed CVP graph is given in Exhibit 5–2. The anticipated profit or loss at any given level of sales is measured by the vertical distance
between the total revenue line (sales) and the total expense line (variable expense plus
fixed expense).

The break-even point is where the total revenue and total expense lines cross. The
break-even point of 350 speakers in Exhibit 5–2 agrees with the break-even point computed earlier.
As discussed earlier, when sales are below the break-even point—in this case, 350
units—the company suffers a loss. Note that the loss (represented by the vertical distance

sales are above the break-even point, the company earns a profit and the size of the profit
(represented by the vertical distance between the total revenue and total expense lines)
increases as sales increase.
An even simpler form of the CVP graph, which we call a profit graph, is presented in
Exhibit 5–3. That graph is based on the following equation:
Profit 5 Unit CM 3 Q 2 Fixed expenses
In the case of Acoustic Concepts, the equation can be expressed as:
Profit 5 $100 3 Q 2 $35,000
LO5–3
Use the contribution margin
ratio (CM ratio) to compute
changes in contribution margin
and net operating income
resulting from changes in sales
volume.
Because this is a linear equation, it plots as a single straight line. To plot the line, compute the profit at two different sales volumes, plot the points, and then connect them
with a straight line. For example, when the sales volume is zero (i.e., Q 5 0), the
profit is 2 $35,000 (5 $100 3 0 2 $35,000). When Q is 600, the profit is $25,000
(5 $100 3 600 2 $35,000). These two points are plotted in Exhibit 5–3 and a straight
line has been drawn through them.
The break-even point on the profit graph is the volume of sales at which profit is zero
and is indicated by the dashed line on the graph. Note that the profit steadily increases to
the right of the break-even point as the sales volume increases and that the loss becomes
steadily worse to the left of the break-even point as the sales volume decreases.
Contribution Margin Ratio (CM Ratio)
In the previous section, we explored how cost-volume-profit relationships can be visualized. In this section, we show how the contribution margin ratio can be used in costvolume-profit calculations. As the first step, we have added a column to Acoustic Concepts’
Cost-Volume-Profit Relationships
contribution format income statement in which sales revenues, variable expenses, and
contribution margin are expressed as a percentage of sales:

5,000
The contribution margin as a percentage of sales is referred to as the contribution
margin ratio (CM ratio). This ratio is computed as follows:
Contribution margin
CM ratio 5 _________________
Sales
For Acoustic Concepts, the computations are:
Total contribution margin
$40,000
CM ratio 5 _____________________ 5 ________ 5 40%
Total sales
$100,000
In a company such as Acoustic Concepts that has only one product, the CM ratio can also
be computed on a per unit basis as follows:
Unit contribution margin $100
CM ratio 5 _____________________ 5 _____ 5 40%
Unit selling price
$250
The CM ratio shows how the contribution margin will be affected by a change in
total sales. Acoustic Concepts’ CM ratio of 40% means that for each dollar increase in
sales, total contribution margin will increase by 40 cents ($1 sales 3 CM ratio of 40%).
Net operating income will also increase by 40 cents, assuming that fixed costs are not
affected by the increase in sales. Generally, the effect of a change in sales on the contribution margin is expressed in equation form as:
Change in contribution margin 5 CM ratio 3 Change in sales
As this illustration suggests, the impact on net operating income of any given dollar
change in total sales can be computed by applying the CM ratio to the dollar change.
For example, if Acoustic Concepts plans a $30,000 increase in sales during the coming month, the contribution margin should increase by $12,000 ($30,000 increase in
sales 3 CM ratio of 40%). As we noted above, net operating income will also increase by
$12,000 if fixed costs do not change. This is verified by the following table:

Chapter 5
The relation between profit and the CM ratio can also be expressed using the following equations:
Profit 5 CM ratio 3 Sales 2 Fixed expenses2
or, in terms of changes,
Change in profit 5 CM ratio 3 Change in sales 2 Change in fixed expenses
For example, at sales of $130,000, the profit is expected to be $17,000 as shown below:
Profit 5 CM ratio 3 Sales 2 Fixed expenses
5 0.40 3 $130,000 2 $35,000
5 $52,000 2 $35,000 5 $17,000
Again, if you are comfortable with algebra, this approach will often be quicker and easier
than constructing contribution format income statements.
The CM ratio is particularly valuable in situations where the dollar sales of one product
must be traded off against the dollar sales of another product. In this situation, products that
yield the greatest amount of contribution margin per dollar of sales should be emphasized.

Some Applications of CVP Concepts
Show the effects on net
operating income of changes
in variable costs, fixed costs,
selling price, and volume.
Bob Luchinni, the accountant at Acoustic Concepts, wanted to demonstrate to the company’s president Prem Narayan how the concepts developed on the preceding pages can
be used in planning and decision making. Bob gathered the following basic data:

Contribution margin . . . . . . . . .

Recall that fixed expenses are $35,000 per month. Bob Luchinni will use these data
to show the effects of changes in variable costs, fixed costs, sales price, and sales volume
on the company’s profitability in a variety of situations.
Before proceeding further, however, we need to introduce another concept—the variable expense ratio. The variable expense ratio is the ratio of variable expenses to sales.
It can be computed by dividing the total variable expenses by the total sales, or in a single
product analysis, it can be computed by dividing the variable expenses per unit by the
unit selling price. In the case of Acoustic Concepts, the variable expense ratio is 0.60;
that is, variable expense is 60% of sales. Expressed as an equation, the definition of the
variable expense ratio is:
Variable expenses
Variable expense ratio 5 _______________
Sales
2
This equation can be derived using the basic profit equation and the definition of the CM ratio as
follows:
Profit 5 (Sales 2 Variable expenses) 2 Fixed expenses
Profit 5 Contribution margin 2 Fixed expenses
Contribution margin
Profit 5 _________________ 3 Sales 2 Fixed expenses
Sales
Profit 5 CM ratio 3 Sales 2 Fixed expenses
Cost-Volume-Profit Relationships
This leads to a useful equation that relates the CM ratio to the variable expense ratio
as follows:

CM ratio 5 1 2 Variable expense ratio
Change in Fixed Cost and Sales Volume Acoustic Concepts is currently
selling 400 speakers per month at $250 per speaker for total monthly sales of $100,000.
The sales manager feels that a $10,000 increase in the monthly advertising budget would
increase monthly sales by $30,000 to a total of 520 units. Should the advertising budget
be increased? The table below shows the financial impact of the proposed change in the
monthly advertising budget.

Assuming no other factors need to be considered, the increase in the advertising budget should be approved because it would increase net operating income by $2,000. There
are two shorter ways to arrive at this solution. The first alternative solution follows:
Alternative Solution 1
Expected total contribution margin:

Chapter 5
Notice that this approach does not depend on knowledge of previous sales. Also note
that it is unnecessary under either shorter approach to prepare an income statement. Both
of the alternative solutions involve incremental analysis—they consider only the costs
and revenues that will change if the new program is implemented. Although in each case
a new income statement could have been prepared, the incremental approach is simpler
and more direct and focuses attention on the specific changes that would occur as a result
of the decision.
Change in Variable Costs and Sales Volume Refer to the original data.
Recall that Acoustic Concepts is currently selling 400 speakers per month. Prem is considering the use of higher-quality components, which would increase variable costs (and
thereby reduce the contribution margin) by $10 per speaker. However, the sales manager
predicts that using higher-quality components would increase sales to 480 speakers per
month. Should the higher-quality components be used?
The $10 increase in variable costs would decrease the unit contribution margin by
$10—from $100 down to $90.
Solution
Expected total contribution margin with higher-quality components:
480 speakers 3 $90 per speaker . . . . . . . . . . . . . . . .
$43,200
Present total contribution margin:
400 speakers 3 $100 per speaker . . . . . . . . . . . . . . .
40,000
$ 3,200
Increase in total contribution margin . . . . . . . . . . . . . . . .
According to this analysis, the higher-quality components should be used. Because
fixed costs would not change, the $3,200 increase in contribution margin shown above
should result in a $3,200 increase in net operating income.
Change in Fixed Cost, Selling Price, and Sales Volume Refer to the
original data and recall again that Acoustic Concepts is currently selling 400 speakers per
month. To increase sales, the sales manager would like to cut the selling price by $20 per
speaker and increase the advertising budget by $15,000 per month. The sales manager
believes that if these two steps are taken, unit sales will increase by 50% to 600 speakers
per month. Should the changes be made?
A decrease in the selling price of $20 per speaker would decrease the unit contribution margin by $20 down to $80.
Solution
Expected total contribution margin with lower selling price:
600 speakers 3 $80 per speaker . . . . . . . . . . . . . . . .
Present total contribution margin:
400 speakers 3 $100 per speaker . . . . . . . . . . . . . . .

Change in Variable Cost, Fixed Cost, and Sales Volume Refer to
Acoustic Concepts’ original data. As before, the company is currently selling 400 speakers per month. The sales manager would like to pay salespersons a sales commission of
$15 per speaker sold, rather than the flat salaries that now total $6,000 per month. The
sales manager is confident that the change would increase monthly sales by 15% to 460
speakers per month. Should the change be made?
Solution Changing the sales staff’s compensation from salaries to commissions
would affect both fixed and variable expenses. Fixed expenses would decrease by $6,000,
from $35,000 to $29,000. Variable expenses per unit would increase by $15, from $150 to
$165, and the unit contribution margin would decrease from $100 to $85.

Change in Selling Price Refer to the original data where Acoustic Concepts is
currently selling 400 speakers per month. The company has an opportunity to make a
bulk sale of 150 speakers to a wholesaler if an acceptable price can be negotiated. This
sale would not disturb the company’s regular sales and would not affect the company’s
total fixed expenses. What price per speaker should be quoted to the wholesaler if Acoustic Concepts is seeking a profit of $3,000 on the bulk sale?

MANAGING RISK IN THE BOOK PUBLISHING INDUSTRY
Greenleaf Book Group is a book publishing company in Austin, Texas, that attracts authors
who are willing to pay publishing costs and forgo up-front advances in exchange for a larger
royalty rate on each book sold. For example, assume a typical publisher prints 10,000 copies of a new book that it sells for $12.50 per unit. The publisher pays the author an advance
of $20,000 to write the book and then incurs $60,000 of expenses to market, print, and edit
the book. The publisher also pays the author a 20% royalty (or $2.50 per unit) on each book
sold above 8,000 units. In this scenario, the publisher must sell 6,400 books to break even
(5 $80,000 in fixed costs 4 $12.50 per unit). If all 10,000 copies are sold, the author earns
$25,000 (5 $20,000 advance 1 2,000 copies 3 $2.50) and the publisher earns $40,000
(5 $125,000 2 $60,000 2 $20,000 2 $5,000).
Greenleaf alters the financial arrangement described above by requiring the author to assume
the risk of poor sales. It pays the author a 70% royalty on all units sold (or $8.75 per unit),
but the author forgoes the $20,000 advance and pays Greenleaf $60,000 to market, print, and
edit the book. If the book flops, the author fails to recover her production costs. If all 10,000 units
are sold, the author earns $27,500 (5 $10,000 units 3 $8.75 2 $60,000) and Greenleaf earns
$37,500 (5 10,000 units 3 ($12.50 2 $8.75)).

Break-Even and Target Profit Analysis
Managers use break-even and target profit analysis to answer questions such as how
much would we have to sell to avoid incurring a loss or how much would we have to sell
to make a profit of $10,000 per month? We’ll discuss break-even analysis first followed
by target profit analysis.
Break-Even Analysis
LO5–5
Determine the break-even point.
Earlier in the chapter we defined the break-even point as the level of sales at which the
company’s profit is zero. To calculate the break-even point (in unit sales and dollar sales),
managers can use either of two approaches, the equation method or the formula method.
We’ll demonstrate both approaches using the data from Acoustic Concepts.
Cost-Volume-Profit Relationships
The Equation Method The equation method relies on the basic profit equation
introduced earlier in the chapter. Since Acoustic Concepts has only one product, we’ll
use the contribution margin form of this equation to perform the break-even calculations.
Remembering that Acoustic Concepts’ unit contribution margin is $100, and its fixed
expenses are $35,000, the company’s break-even point is computed as follows:
Profit 5 Unit CM 3 Q 2 Fixed expense
$0 5 $100 3 Q 2 $35,000
$100 3 Q 5 $0 1 $35,000
Q 5 $35,000 4 $100
Q 5 350
Thus, as we determined earlier in the chapter, Acoustic Concepts will break even (or earn
zero profit) at a sales volume of 350 speakers per month.
The Formula Method The formula method is a shortcut version of the equation
method. It centers on the idea discussed earlier in the chapter that each unit sold provides
a certain amount of contribution margin that goes toward covering fixed expenses. In a
single product situation, the formula for computing the unit sales to break even is:
Fixed expenses3
Units sales to break even 5 ______________
Unit CM
In the case of Acoustic Concepts, the unit sales needed to break even is computed as follows:
Fixed expenses
Units sales to break even 5 _____________
Unit CM
$35,000
5 _______
$100
5 350
Notice that 350 units is the same answer that we got when using the equation method. This
will always be the case because the formula method and equation method are mathematically equivalent. The formula method simply skips a few steps in the equation method.
Break-Even in Dollar Sales In addition to finding the break-even point in unit
sales, we can also find the break-even point in dollar sales using three methods. First, we
could solve for the break-even point in unit sales using the equation method or formula
method and then simply multiply the result by the selling price. In the case of Acoustic
Concepts, the break-even point in dollar sales using this approach would be computed as
350 speakers 3 $250 per speaker, or $87,500 in total sales.
Second, we can use the equation method to compute the break-even point in dollar
sales. Remembering that Acoustic Concepts’ contribution margin ratio is 40% and its
fixed expenses are $35,000, the equation method calculates the break-even point in dollar
sales as follows:
Profit 5 CM ratio 3 Sales 2 Fixed expenses
$0 5 0.40 3 Sales 2 $35,000
0.40 3 Sales 5 $0 1 $35,000
Sales 5 $35,000 4 0.40
Sales 5 $87,500
3
This formula can be derived as follows:
Profit 5 Unit CM 3 Q 2 Fixed expenses
$0 5 Unit CM 3 Q 2 Fixed expenses
Unit CM 3 Q 5 $0 1 Fixed expenses
Q 5 Fixed expenses 4 Unit CM
201
202
Chapter 5
Third, we can use the formula method to compute the dollar sales needed to break
even as shown below:
Fixed expenses4
Dollar sales to break even 5 ______________
CM ratio
In the case of Acoustic Concepts, the computations are performed as follows:
Fixed expenses
Dollar sales to break even 5 _____________
CM ratio
$35,000
5 _______
0.40
5 $87,500
Again, you’ll notice that the break-even point in dollar sales ($87,500) is the same
under all three methods. This will always be the case because these methods are mathematically equivalent.
LO5–6
Target Profit Analysis
Determine the level of sales
needed to achieve a desired
target profit.
Target profit analysis is one of the key uses of CVP analysis. In target profit analysis,
we estimate what sales volume is needed to achieve a specific target profit. For example,
suppose Prem Narayan of Acoustic Concepts would like to estimate the sales needed to
attain a target profit of $40,000 per month. To determine the unit sales and dollar sales
needed to achieve a target profit, we can rely on the same two approaches that we have
been discussing thus far, the equation method or the formula method.
The Equation Method To compute the unit sales required to achieve a target
profit of $40,000 per month, Acoustic Concepts can use the same profit equation that was
used for its break-even analysis. Remembering that the company’s contribution margin
per unit is $100 and its total fixed expenses are $35,000, the equation method could be
applied as follows:
Profit 5 Unit CM 3 Q 2 Fixed expense
$40,000 5 $100 3 Q 2 $35,000
$100 3 Q 5 $40,000 1 $35,000
Q 5 $75,000 4 $100
Q 5 750
Thus, the target profit can be achieved by selling 750 speakers per month. Notice that
the only difference between this equation and the equation used for Acoustic Concepts’
break-even calculation is the profit figure. In the break-even scenario, the profit is $0,
whereas in the target profit scenario the profit is $40,000.

This formula can be derived as follows:
Profit 5 CM ratio 3 Sales 2 Fixed expenses
$0 5 CM ratio 3 Sales 2 Fixed expenses
CM ratio 3 Sales 5 $0 1 Fixed expenses
Sales 5 Fixed expenses 4 CM ratio
Cost-Volume-Profit Relationships
The Formula Method In general, in a single product situation, we can compute
the sales volume required to attain a specific target profit using the following formula:
Target profit 1 Fixed expenses
Units sales to attain the target profit 5 __________________________
Unit CM
In the case of Acoustic Concepts, the unit sales needed to attain a target profit of
40,000 is computed as follows:
Target profit 1 Fixed expenses
Units sales to attain the target profit 5 _________________________
Unit CM
$40,000 1 $35,000
5 ________________
$100
5 750
Target Profit Analysis in Terms of Dollar Sales When quantifying the
dollar sales needed to attain a target profit we can apply the same three methods that we
used for calculating the dollar sales needed to break even. First, we can solve for the unit
sales needed to attain the target profit using the equation method or formula method and
then simply multiply the result by the selling price. In the case of Acoustic Concepts,
the dollar sales to attain its target profit would be computed as 750 speakers 3 $250 per
speaker, or $187,500 in total sales.
Second, we can use the equation method to compute the dollar sales needed to attain
the target profit. Remembering that Acoustic Concepts’ target profit is $40,000, its contribution margin ratio is 40%, and its fixed expenses are $35,000, the equation method
calculates the answer as follows:
Profit 5 CM ratio 3 Sales 2 Fixed expenses
$40,000 5 0.40 3 Sales 2 $35,000
0.40 3 Sales 5 $40,000 1 $35,000
Sales 5 $75,000 4 0.40
Sales 5 $187,500
Third, we can use the formula method to compute the dollar sales needed to attain the
target profit as shown below:
Target profit 1 Fixed expenses
Dollar sales to attain a target profit 5 __________________________
CM ratio
In the case of Acoustic Concepts, the computations would be:
Target profit 1 Fixed expenses
Dollar sales to attain a target profit 5 __________________________
CM ratio
$40,000 1 $35,000
5 ________________
$0.40
5 $187,500
Again, you’ll notice that the answers are the same regardless of which method we
use. This is because all of the methods discussed are simply different roads to the same
destination.

SNAP FITNESS GROWS IN A WEAK ECONOMY
When Bally’s Total Fitness was filing for bankruptcy, Snap Fitness was expanding to more than
900 clubs in the United States with 400,000 members. The secret to Snap Fitness’ success is its
“no frills” approach to exercise. Each club typically has five treadmills, two stationary bikes, five
elliptical machines, and weight equipment while bypassing amenities such as on-site child care,
juice bars, and showers. Each club is usually staffed only 25–40 hours per week and it charges a
membership fee of $35 per month.
To open a new Snap Fitness location, each franchise owner has an initial capital outlay
of $120,000 for various types of equipment and a one-time licensing fee of $15,000. The
franchisee also pays Snap (the parent company) a royalty fee of $400 per month plus $0.50
for each membership. Snap also collects one-time fees of $5 for each new member’s “billing
setup” and $5 for each security card issued. If a new club attracts 275 members, it can break
even in as little as three months. Can you estimate the underlying calculations related to this
break-even point?

The Margin of Safety
LO5–7
Compute the margin of safety
and explain its significance.
The margin of safety is the excess of budgeted or actual sales dollars over the break-even
volume of sales dollars. It is the amount by which sales can drop before losses are
incurred. The higher the margin of safety, the lower the risk of not breaking even and
incurring a loss. The formula for the margin of safety is:
Margin of safety in dollars 5 Total budgeted (or actual) sales 2 Break-even sales
The margin of safety can also be expressed in percentage form by dividing the margin of safety in dollars by total dollar sales:
Margin of safety in dollars
Margin of safety percentage 5 __________________________________
Total budgeted (or actual) sales in dollars
The calculation of the margin of safety for Acoustic Concepts is:
Sales (at the current volume of 400 speakers) (a) . . . . . . .
Break-even sales (at 350 speakers) . . . . . . . . . . . . . . . . . .
Margin of safety in dollars (b) . . . . . . . . . . . . . . . . . . . . . . .

87,500
$ 12,500
Margin of safety percentage, (b) 4 (a) . . . . . . . . . . . . . . . .
12.5%
This margin of safety means that at the current level of sales and with the company’s current prices and cost structure, a reduction in sales of $12,500, or 12.5%, would result in
just breaking even.
In a single-product company like Acoustic Concepts, the margin of safety can also
be expressed in terms of the number of units sold by dividing the margin of safety in
dollars by the selling price per unit. In this case, the margin of safety is 50 speakers
($12,500 4 $250 per speaker 5 50 speakers).

Sam Calagione owns Dogfish Head Craft Brewery, a microbrewery in Rehobeth Beach, Delaware.
He charges distributors as much as $100 per case for his premium beers such as World Wide
Stout. The high-priced microbrews bring in $800,000 in operating income on revenue of $7 million.
Calagione reports that his raw ingredients and labor costs for one case of World Wide Stout are
$30 and $16, respectively. Bottling and packaging costs are $6 per case. Gas and electric costs
are about $10 per case.
If we assume that World Wide Stout is representative of all Dogfish microbrews, then we can
compute the company’s margin of safety in five steps. First, variable cost as a percentage of sales
is 62% [($30 1 $16 1 $6 1 $10)/$100]. Second, the contribution margin ratio is 38% (1 2 0.62).
Third, Dogfish’s total fixed cost is $1,860,000 [($7,000,000 3 0.38) 2 $800,000]. Fourth, the
break-even point in dollar sales is $4,894,737 ($1,860,000/0.38). Fifth, the margin of safety is
$2,105,263 ($7,000,000 2 $4,894,737).

Prem Narayan and Bob Luchinni met to discuss the results of Bob’s analysis.
Prem: Bob, everything you have shown me is pretty clear. I can see what impact the
sales manager’s suggestions would have on our profits. Some of those suggestions
are quite good and others are not so good. I am concerned that our margin of safety
is only 50 speakers. What can we do to increase this number?
Bob: Well, we have to increase total sales or decrease the break-even point or both.
Prem: And to decrease the break-even point, we have to either decrease our fixed
expenses or increase our unit contribution margin?
Bob: Exactly.
Prem: And to increase our unit contribution margin, we must either increase our selling
price or decrease the variable cost per unit?
Bob: Correct.
Prem: So what do you suggest?
Bob: Well, the analysis doesn’t tell us which of these to do, but it does indicate we have
a potential problem here.
Prem: If you don’t have any immediate suggestions, I would like to call a general meeting next week to discuss ways we can work on increasing the margin of safety. I
think everyone will be concerned about how vulnerable we are to even small downturns in sales.
MANAGERIAL
ACCOUNTING IN ACTION
THE WRAP-UP
CVP Considerations in Choosing a Cost Structure
Cost structure refers to the relative proportion of fixed and variable costs in an organization. Managers often have some latitude in trading off between these two types of costs.
For example, fixed investments in automated equipment can reduce variable labor costs.
In this section, we discuss the choice of a cost structure. We also introduce the concept of
operating leverage.
Cost Structure and Profit Stability
Which cost structure is better—high variable costs and low fixed costs, or the opposite?
No single answer to this question is possible; each approach has its advantages. To show
what we mean, refer to the following contribution format income statements for two
206

blueberry farms. Bogside Farm depends on migrant workers to pick its berries by hand,
whereas Sterling Farm has invested in expensive berry-picking machines. Consequently,
Bogside Farm has higher variable costs, but Sterling Farm has higher fixed costs:

Which farm has the better cost structure? The answer depends on many factors,
including the long-run trend in sales, year-to-year fluctuations in the level of sales, and
the attitude of the owners toward risk. If sales are expected to exceed $100,000 in the
future, then Sterling Farm probably has the better cost structure. The reason is that its CM
ratio is higher, and its profits will therefore increase more rapidly as sales increase. To
illustrate, assume that each farm experiences a 10% increase in sales without any increase
in fixed costs. The new income statements would be as follows:
Bogside Farm

Sterling Farm has experienced a greater increase in net operating income due to its higher
CM ratio even though the increase in sales was the same for both farms.
What if sales drop below $100,000? What are the farms’ break-even points? What are
their margins of safety? The computations needed to answer these questions are shown
below using the formula method:

Bogside Farm’s margin of safety is greater and its contribution margin ratio is lower
than Sterling Farm. Therefore, Bogside Farm is less vulnerable to downturns than Sterling
Farm. Due to its lower contribution margin ratio, Bogside Farm will not lose contribution
margin as rapidly as Sterling Farm when sales decline. Thus, Bogside Farm’s profit will
be less volatile. We saw earlier that this is a drawback when sales increase, but it provides
Cost-Volume-Profit Relationships
207
more protection when sales drop. And because its break-even point is lower, Bogside
Farm can suffer a larger sales decline before losses emerge.
To summarize, without knowing the future, it is not obvious which cost structure
is better. Both have advantages and disadvantages. Sterling Farm, with its higher fixed
costs and lower variable costs, will experience wider swings in net operating income as
sales fluctuate, with greater profits in good years and greater losses in bad years. Bogside
Farm, with its lower fixed costs and higher variable costs, will enjoy greater profit stability and will be more protected from losses during bad years, but at the cost of lower net
operating income in good years.
Operating Leverage
A lever is a tool for multiplying force. Using a lever, a massive object can be moved with
only a modest amount of force. In business, operating leverage serves a similar purpose.
Operating leverage is a measure of how sensitive net operating income is to a given
percentage change in dollar sales. Operating leverage acts as a multiplier. If operating
leverage is high, a small percentage increase in sales can produce a much larger percentage increase in net operating income.
Operating leverage can be illustrated by returning to the data for the two blueberry
farms. We previously showed that a 10% increase in sales (from $100,000 to $110,000 in
each farm) results in a 70% increase in the net operating income of Sterling Farm (from
$10,000 to $17,000) and only a 40% increase in the net operating income of Bogside
Farm (from $10,000 to $14,000). Thus, for a 10% increase in sales, Sterling Farm experiences a much greater percentage increase in profits than does Bogside Farm. Therefore,
Sterling Farm has greater operating leverage than Bogside Farm.
The degree of operating leverage at a given level of sales is computed by the following formula:
Contribution margin
Degree of operating leverage 5 __________________
Net operating income
The degree of operating leverage is a measure, at a given level of sales, of how a percentage change in sales volume will affect profits. To illustrate, the degree of operating leverage for the two farms at $100,000 sales would be computed as follows:
$40,000
Bogside Farm: _______ 5 4
$10,000
$70,000
Sterling Farm: _______ 5 7
$10,000
Because the degree of operating leverage for Bogside Farm is 4, the farm’s net operating income grows four times as fast as its sales. In contrast, Sterling Farm’s net operating
income grows seven times as fast as its sales. Thus, if sales increase by 10%, then we can
expect the net operating income of Bogside Farm to increase by four times this amount,
or by 40%, and the net operating income of Sterling Farm to increase by seven times this
amount, or by 70%. In general, this relation between the percentage change in sales and the
percentage change in net operating income is given by the following formula:
Percentage
Percentage change in
Degree of

net operating income operating leverage change in sales
Bogside Farm: Percentage change in net operating income 5 4 3 10% 5 40%
Sterling Farm: Percentage change in net operating income 5 7 3 10% 5 70%
What is responsible for the higher operating leverage at Sterling Farm? The only
difference between the two farms is their cost structure. If two companies have the same
total revenue and same total expense but different cost structures, then the company with
LO5–8
Compute the degree of
operating leverage at a
particular level of sales and
explain how it can be used
to predict changes in net
operating income.
208
Chapter 5
the higher proportion of fixed costs in its cost structure will have higher operating leverage. Referring back to the original example on page 206, when both farms have sales of
$100,000 and total expenses of $90,000, one-third of Bogside Farm’s costs are fixed but
two-thirds of Sterling Farm’s costs are fixed. As a consequence, Sterling’s degree of operating leverage is higher than Bogside’s.
The degree of operating leverage is not a constant; it is greatest at sales levels near

Thus, a 10% increase in sales would increase profits by only 15% (10% 3 1.5) if sales
were previously $225,000, as compared to the 40% increase we computed earlier at the
$100,000 sales level. The degree of operating leverage will continue to decrease the farther the company moves from its break-even point. At the break-even point, the degree
of operating leverage is infinitely large ($30,000 contribution margin 4 $0 net operating
income 5 `).
The degree of operating leverage can be used to quickly estimate what impact various
percentage changes in sales will have on profits, without the necessity of preparing detailed
income statements. As shown by our examples, the effects of operating leverage can be
dramatic. If a company is near its break-even point, then even small percentage increases
in sales can yield large percentage increases in profits. This explains why management will
often work very hard for only a small increase in sales volume. If the degree of operating
leverage is 5, then a 6% increase in sales would translate into a 30% increase in profits.

THE DANGERS OF A HIGH DEGREE OF OPERATING LEVERAGE
In recent years, computer chip manufacturers have poured more than $75 billion into constructing new manufacturing facilities to meet the growing demand for digital devices such as iPhones
and Blackberrys. Because 70% of the costs of running these facilities are fixed, a sharp drop in
customer demand forces these companies to choose between two undesirable options. They can
slash production levels and absorb large amounts of unused capacity costs, or they can continue
producing large volumes of output in spite of shrinking demand, thereby flooding the market with
excess supply and lowering prices. Either choice distresses investors who tend to shy away from
computer chip makers in economic downturns.

Structuring Sales Commissions
Companies usually compensate salespeople by paying them a commission based on
sales, a salary, or a combination of the two. Commissions based on sales dollars can lead
to lower profits. To illustrate, consider Pipeline Unlimited, a producer of surfing equipment. Salespersons sell the company’s products to retail sporting goods stores throughout
North America and the Pacific Basin. Data for two of the company’s surfboards, the XR7
and Turbo models, appear below:
Model

Variable expenses . . . . . . .
Contribution margin . . . . . .
XR7
Turbo
$695
344
$351
$749
410
$339
Which model will salespeople push hardest if they are paid a commission of 10% of sales
revenue? The answer is the Turbo because it has the higher selling price and hence the
larger commission. On the other hand, from the standpoint of the company, profits will
be greater if salespeople steer customers toward the XR7 model because it has the higher
contribution margin.
To eliminate such conflicts, commissions can be based on contribution margin rather
than on selling price. If this is done, the salespersons will want to sell the mix of products
that maximizes contribution margin. Providing that fixed costs are not affected by the
sales mix, maximizing the contribution margin will also maximize the company’s profit.5
In effect, by maximizing their own compensation, salespersons will also maximize the
company’s profit.
Sales Mix
Before concluding our discussion of CVP concepts, we need to consider the impact of
changes in sales mix on a company’s profit.
The Definition of Sales Mix
The term sales mix refers to the relative proportions in which a company’s products are
sold. The idea is to achieve the combination, or mix, that will yield the greatest profits.
Most companies have many products, and often these products are not equally profitable.
Hence, profits will depend to some extent on the company’s sales mix. Profits will be
greater if high-margin rather than low-margin items make up a relatively large proportion
of total sales.
Changes in the sales mix can cause perplexing variations in a company’s profits. A
shift in the sales mix from high-margin items to low-margin items can cause total profits
to decrease even though total sales may increase. Conversely, a shift in the sales mix
from low-margin items to high-margin items can cause the reverse effect—total profits
may increase even though total sales decrease. It is one thing to achieve a particular sales
volume; it is quite another to sell the most profitable mix of products.
5
This also assumes the company has no production constraint. If it does, the sales commissions should
be modified. See the Profitability Appendix at the end of the book.

NETBOOK SALES CANNIBALIZE PC SALES
When computer manufacturers introduced the “netbook,” they expected it to serve as a consumer’s
third computer—complementing home and office personal computers (PCs) rather than replacing
them. However, when the economy soured many customers decided to buy lower-priced netbooks
instead of PCs, which in turn adversely affected the financial performance of many companies. For
example, when Microsoft failed to achieve its sales goals, the company partially blamed growing
netbook sales and declining PC sales for its troubles. Microsoft’s Windows operating system for
netbooks sells for $15–$25 per device, which is less than half the cost of the company’s least
expensive Windows operating system for PCs.

Sales Mix and Break-Even Analysis
If a company sells more than one product, break-even analysis is more complex than discussed to this point. The reason is that different products will have different selling prices,
different costs, and different contribution margins. Consequently, the break-even point
depends on the mix in which the various products are sold. To illustrate, consider Virtual
Journeys Unlimited, a small company that sells two DVDs: the Monuments DVD, a tour
of the United States’ most popular National Monuments; and the Parks DVD, which
tours the United States’ National Parks. The company’s September sales, expenses, and
break-even point are shown in Exhibit 5–4.
As shown in the exhibit, the break-even point is $60,000 in sales, which was computed by dividing the company’s fixed expenses of $27,000 by its overall CM ratio
of 45%. However, this is the break-even only if the company’s sales mix does not
change. Currently, the Monuments DVD is responsible for 20% and the Parks DVD
for 80% of the company’s dollar sales. Assuming this sales mix does not change, if
total sales are $60,000, the sales of the Monuments DVD would be $12,000 (20% of
$60,000) and the sales of the Parks DVD would be $48,000 (80% of $60,000). As
shown in Exhibit 5–4, at these levels of sales, the company would indeed break even.
But $60,000 in sales represents the break-even point for the company only if the sales
mix does not change. If the sales mix changes, then the break-even point will also
usually change. This is illustrated by the results for October in which the sales mix
shifted away from the more profitable Parks DVD (which has a 50% CM ratio) toward
the less profitable Monuments CD (which has a 25% CM ratio). These results appear
in Exhibit 5–5.
Although sales have remained unchanged at $100,000, the sales mix is exactly
the reverse of what it was in Exhibit 5–4, with the bulk of the sales now coming from
the less profitable Monuments DVD. Notice that this shift in the sales mix has caused
both the overall CM ratio and total profits to drop sharply from the prior month even
though total sales are the same. The overall CM ratio has dropped from 45% in September to only 30% in October, and net operating income has dropped from $18,000
to only $3,000. In addition, with the drop in the overall CM ratio, the company’s
break-even point is no longer $60,000 in sales. Because the company is now realizing
less average contribution margin per dollar of sales, it takes more sales to cover the
same amount of fixed costs. Thus, the break-even point has increased from $60,000 to
$90,000 in sales per year.
In preparing a break-even analysis, an assumption must be made concerning the
sales mix. Usually the assumption is that it will not change. However, if the sales mix
is expected to change, then this must be explicitly considered in any CVP computations.

Summary
CVP analysis is based on a simple model of how profits respond to prices, costs, and volume. This
model can be used to answer a variety of critical questions such as what is the company’s breakeven volume, what is its margin of safety, and what is likely to happen if specific changes are made
in prices, costs, and volume.
A CVP graph depicts the relationships between unit sales on the one hand and fixed expenses,
variable expenses, total expenses, total sales, and profits on the other hand. The profit graph is
simpler than the CVP graph and shows how profits depend on sales. The CVP and profit graphs are
useful for developing intuition about how costs and profits respond to changes in sales.
The contribution margin ratio is the ratio of the total contribution margin to total sales. This
ratio can be used to quickly estimate what impact a change in total sales would have on net operating income. The ratio is also useful in break-even analysis.
Break-even analysis is used to estimate how much sales would have to be to just break even.
The unit sales required to break even can be estimated by dividing the fixed expense by the unit
contribution margin. Target profit analysis is used to estimate how much sales would have to be to
attain a specified target profit. The unit sales required to attain the target profit can be estimated by
dividing the sum of the target profit and fixed expense by the unit contribution margin.
The margin of safety is the amount by which the company’s current sales exceeds breakeven sales.
The degree of operating leverage allows quick estimation of what impact a given percentage
change in sales would have on the company’s net operating income. The higher the degree of operating leverage, the greater is the impact on the company’s profits. The degree of operating leverage
is not constant—it depends on the company’s current level of sales.
The profits of a multiproduct company are affected by its sales mix. Changes in the sales mix
can affect the break-even point, margin of safety, and other critical factors.

Yes, based on these data, the changes should be made. The changes increase the company’s net operating income from the present $60,000 to $78,000 per year. Although the
changes also result in a higher break-even point (17,500 units as compared to the present
16,000 units), the company’s margin of safety actually becomes greater than before:

As shown in (5) on the prior page, the company’s present margin of safety is only $240,000. Thus,
several benefits will result from the proposed changes.

b. Thad is worried about the selling price. Rumors are circulating that other retro brands
of cycles may be revived. If so, the selling price for the Western Hombre would have
to be reduced to $9,000 to compete effectively. In that event, Thad would also reduce
fixed expenses by $300,000 by reducing advertising expenses, but he still hopes to sell
600 units per year. Do you think this is a good plan? Explain. Also, explain the degree of
operating leverage that appears on your worksheet.

Northwood Company manufactures basketballs. The company has a ball that sells for $25. At
present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus,
variable expenses are high, totaling $15 per ball, of which 60% is direct labor cost.
Last year, the company sold 30,000 of these balls, with the following results:

Compute (a) the CM ratio and the break-even point in balls, and (b) the degree of operating
leverage at last year’s sales level.
Due to an increase in labor rates, the company estimates that variable expenses will increase
by $3 per ball next year. If this change takes place and the selling price per ball remains constant at $25, what will be the new CM ratio and break-even point in balls?
Refer to the data in (2) above. If the expected change in variable expenses takes place, how
many balls will have to be sold next year to earn the same net operating income, $90,000, as
last year?
Refer again to the data in (2) above. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio
as last year, what selling price per ball must it charge next year to cover the increased labor
costs?
Refer to the original data. The company is discussing the construction of a new, automated
manufacturing plant. The new plant would slash variable expenses per ball by 40%, but it
would cause fixed expenses per year to double. If the new plant is built, what would be the
company’s new CM ratio and new break-even point in balls?
Refer to the data in (5) above.
a. If the new plant is built, how many balls will have to be sold next year to earn the same
net operating income, $90,000, as last year?
b. Assume the new plant is built and that next year the company manufactures and sells
30,000 balls (the same number as sold last year). Prepare a contribution format income
statement and compute the degree of operating leverage.
c. If you were a member of top management, would you have been in favor of constructing
the new plant? Explain.

income or loss? (Use the incremental approach in preparing your answer.)
Refer to the original data. The sales manager is convinced that a 10% reduction in the selling
price, combined with an increase of $60,000 in the monthly advertising budget, will double
unit sales. What will the new contribution format income statement look like if these changes
are adopted?
Refer to the original data. The Marketing Department thinks that a fancy new package for the
laptop computer battery would help sales. The new package would increase packaging costs
by 75 cents per unit. Assuming no other changes, how many units would have to be sold each
month to earn a profit of $9,750?

The president expects sales to increase by 20% next year. By what percentage should net
operating income increase?
Refer to the original data. Assume that the company sold 18,000 units last year. The sales
manager is convinced that a 10% reduction in the selling price, combined with a $30,000
increase in advertising, would increase annual unit sales by one-third. Prepare two contribution format income statements, one showing the results of last year’s operations and one
showing the results of operations if these changes are made. Would you recommend that the
company do as the sales manager suggests?
Refer to the original data. Assume again that the company sold 18,000 units last year. The president does not want to change the selling price. Instead, he wants to increase the sales commission by $1 per unit. He thinks that this move, combined with some increase in advertising, would
increase annual sales by 25%. By how much could advertising be increased with profits remaining
unchanged? Do not prepare an income statement; use the incremental analysis approach.
PROBLEM 5–24 Break-Even and Target Profit Analysis [LO5–5, LO5–6]
The Shirt Works sells a large variety of tee shirts and sweatshirts. Steve Hooper, the owner, is
thinking of expanding his sales by hiring high school students, on a commission basis, to sell
sweatshirts bearing the name and mascot of the local high school.
These sweatshirts would have to be ordered from the manufacturer six weeks in advance, and
they could not be returned because of the unique printing required. The sweatshirts would cost
Hooper $8 each with a minimum order of 75 sweatshirts. Any additional sweatshirts would have to
be ordered in increments of 75.
Since Hooper’s plan would not require any additional facilities, the only costs associated with
the project would be the costs of the sweatshirts and the costs of the sales commissions. The selling
price of the sweatshirts would be $13.50 each. Hooper would pay the students a commission of
$1.50 for each shirt sold.
Required:

PROBLEM 5–25 Changes in Fixed and Variable Expenses; Break-Even and Target Profit Analysis
[LO5–4, LO5–5, LO5–6]
Neptune Company produces toys and other items for use in beach and resort areas. A small, inflatable toy has come onto the market that the company is anxious to produce and sell. The new toy
will sell for $3 per unit. Enough capacity exists in the company’s plant to produce 16,000 units of
the toy each month. Variable expenses to manufacture and sell one unit would be $1.25, and fixed
expenses associated with the toy would total $35,000 per month.
The company’s Marketing Department predicts that demand for the new toy will exceed
the 16,000 units that the company is able to produce. Additional manufacturing space can be
rented from another company at a fixed expense of $1,000 per month. Variable expenses in the
rented facility would total $1.40 per unit, due to somewhat less efficient operations than in the
main plant.

New equipment has come onto the market that would allow Morton Company to automate a
portion of its operations. Variable expenses would be reduced by $9 per unit. However, fixed
expenses would increase to a total of $225,000 each month. Prepare two contribution format
income statements, one showing present operations and one showing how operations would
appear if the new equipment is purchased. Show an Amount column, a Per Unit column, and
a Percent column on each statement. Do not show percentages for the fixed expenses.
Refer to the income statements in (1) above. For both present operations and the proposed
new operations, compute (a) the degree of operating leverage, (b) the break-even point in
dollar sales, and (c) the margin of safety in both dollar and percentage terms.
Refer again to the data in (1) above. As a manager, what factor would be paramount in your
mind in deciding whether to purchase the new equipment? (Assume that enough funds are
available to make the purchase.)
Refer to the original data. Rather than purchase new equipment, the marketing manager
argues that the company’s marketing strategy should be changed. Rather than pay sales commissions, which are currently included in variable expenses, the company would pay salespersons fixed salaries and would invest heavily in advertising. The marketing manager claims
this new approach would increase unit sales by 30% without any change in selling price; the
company’s new monthly fixed expenses would be $180,000; and its net operating income
would increase by 20%. Compute the break-even point in dollar sales for the company under
the new marketing strategy. Do you agree with the marketing manager’s proposal?

total sales dollars?
Prepare a CVP graph or a profit graph for the store from zero pairs up to 4,000 pairs of sandals
sold each year. Indicate the break-even point on your graph.
Angie has decided that she must earn at least $18,000 the first year to justify her time and

As Barbara handed the statement to Karl Vecci, Pittman’s president, she commented, “I went
ahead and used the agents’ 15% commission rate in completing these statements, but we’ve just
learned that they refuse to handle our products next year unless we increase the commission rate
to 20%.”
“That’s the last straw,” Karl replied angrily. “Those agents have been demanding more and
more, and this time they’ve gone too far. How can they possibly defend a 20% commission rate?”
“They claim that after paying for advertising, travel, and the other costs of promotion, there’s
nothing left over for profit,” replied Barbara.
“I say it’s just plain robbery,” retorted Karl. “And I also say it’s time we dumped those guys and
got our own sales force. Can you get your people to work up some cost figures for us to look at?”
“We’ve already worked them up,” said Barbara. “Several companies we know about pay a
7.5% commission to their own salespeople, along with a small salary. Of course, we would have
to handle all promotion costs, too. We figure our fixed expenses would increase by $2,400,000 per
year, but that would be more than offset by the $3,200,000 (20% 3 $16,000,000) that we would
avoid on agents’ commissions.”

under the old 15% commission rate.”
“It’s even better than that,” explained Barbara. “We can actually save $75,000 a year because
that’s what we’re having to pay the auditing firm now to check out the agents’ reports. So our overall administrative expenses would be less.”
“Pull all of these numbers together and we’ll show them to the executive committee tomorrow,” said Karl. “With the approval of the committee, we can move on the matter immediately.”

Misguided Incentives in the Auto Industry

LEARNING OBJECTIVES
After studying Chapter 6, you should be
able to:
When the economy tanks, automakers, such as General Motors and
Chrysler, often “flood the market” with a supply of vehicles that far exceeds
customer demand. They pursue this course of action even though it tarnishes
their brand image and increases their auto storage costs, tire replacement
costs, customer rebate costs, and advertising costs. This begs the question
why would managers knowingly produce more vehicles than are demanded
by customers?
In the auto industry, a manager’s bonus is often influenced by her company’s reported profits; thus, there is a strong incentive to boost profits by
producing more units. How can this be done you ask? It would seem logical that producing more units would have no impact on profits unless the
units were sold, right? Wrong! As we will discover in this chapter, absorption
costing—the most widely used method of determining product costs—can
artificially increase profits when managers choose to increase the quantity of
units produced. ■

his chapter describes two applications of the contribution for-

mat income statements that were introduced in earlier chapters. First, it explains
how manufacturing companies can prepare variable costing income statements,
which rely on the contribution format, for internal decision making purposes.
The variable costing approach will be contrasted with absorption costing income statements, which were discussed in Chapter 3 and are generally used for external reports.
Ordinarily, variable costing and absorption costing produce different net operating
income figures, and the difference can be quite large. In addition to showing how these
two methods differ, we will describe the advantages of variable costing for internal
reporting purposes and we will show how management decisions can be affected by the
costing method chosen.
Second, the chapter explains how the contribution format can be used to prepare segmented income statements. In addition to companywide income statements, managers
need to measure the profitability of individual segments of their organizations. A segment
is a part or activity of an organization about which managers would like cost, revenue, or
profit data. This chapter explains how to create contribution format income statements
that report profit data for business segments, such as divisions, individual stores, geographic regions, customers, and product lines.
Overview of Variable and Absorption Costing
LO6–1
Explain how variable costing
differs from absorption costing
and compute unit product costs
under each method.
As you begin to read about variable and absorption costing income statements in the
coming pages, focus your attention on three key concepts. First, both income statement formats include product costs and period costs, although they define these cost
classifications differently. Second, variable costing income statements are grounded in
the contribution format. They categorize expenses based on cost behavior—variable
expenses are reported separately from fixed expenses. Absorption costing income statements ignore variable and fixed cost distinctions. Third, as mentioned in the paragraph
above, variable and absorption costing net operating income figures often differ from
one another. The reason for these differences always relates to the fact the variable costing and absorption costing income statements account for fixed manufacturing overhead
differently. Pay very close attention to the two different ways that variable costing and
absorption costing account for fixed manufacturing overhead.
Variable Costing
Under variable costing, only those manufacturing costs that vary with output are
treated as product costs. This would usually include direct materials, direct labor, and
the variable portion of manufacturing overhead. Fixed manufacturing overhead is not
treated as a product cost under this method. Rather, fixed manufacturing overhead is
treated as a period cost and, like selling and administrative expenses, it is expensed in
its entirety each period. Consequently, the cost of a unit of product in inventory or in
cost of goods sold under the variable costing method does not contain any fixed manufacturing overhead cost. Variable costing is sometimes referred to as direct costing or
marginal costing.
Absorption Costing
As discussed in Chapter 3, absorption costing treats all manufacturing costs as product
costs, regardless of whether they are variable or fixed. The cost of a unit of product under
the absorption costing method consists of direct materials, direct labor, and both variable
and fixed manufacturing overhead. Thus, absorption costing allocates a portion of fixed
Variable Costing and Segment Reporting: Tools for Management
235
manufacturing overhead cost to each unit of product, along with the variable manufacturing costs. Because absorption costing includes all manufacturing costs in product costs, it
is frequently referred to as the full cost method.
Selling and Administrative Expenses
Selling and administrative expenses are never treated as product costs, regardless of the
costing method. Thus, under absorption and variable costing, variable and fixed selling and administrative expenses are always treated as period costs and are expensed as
incurred.
Summary of Differences The essential difference between variable costing and
absorption costing, as illustrated in Exhibit 6–1, is how each method accounts for fixed
manufacturing overhead costs—all other costs are treated the same under the two methods. In absorption costing, fixed manufacturing overhead costs are included as part of
the costs of work in process inventories. When units are completed, these costs are transferred to finished goods and only when the units are sold do these costs flow through to
the income statement as part of cost of goods sold. In variable costing, fixed manufacturing overhead costs are considered to be period costs—just like selling and administrative
costs—and are taken immediately to the income statement as period expenses.

As you review the data above, it is important to realize that for the months of January,
February, and March, the selling price per aircraft, variable cost per aircraft, and total
monthly fixed expenses never change. The only variables that change in this example
are the number of units produced (January 5 1 unit produced; February 5 2 units produced; March 5 4 units produced) and the number of units sold (January 5 1 unit sold;
February 5 1 unit sold; March 5 5 units sold).
We will first construct the company’s variable costing income statements for January,
February, and March. Then we will show how the company’s net operating income would
be determined for the same months using absorption costing.

LO6–2
Prepare income statements
using both variable and
absorption costing.
To prepare the company’s variable costing income statements for January, February, and
March we begin by computing the unit product cost. Under variable costing, product
costs consist solely of variable production costs. At Weber Light Aircraft, the variable
production cost per unit is $25,000, determined as follows:

Since each month’s variable production cost is $25,000 per aircraft, the variable costing
cost of goods sold for all three months can be easily computed as follows:

A simple method for understanding how Weber Light Aircraft computed its variable
costing net operating income figures is to focus on the contribution margin per aircraft
sold, which is computed as follows:
Contribution Margin per Aircraft Sold
Selling price per aircraft . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The variable costing net operating income for each period can always be computed by
multiplying the number of units sold by the contribution margin per unit and then subtracting total fixed costs. For Weber Light Aircraft these computations would appear as follows:
Number of aircraft sold . . . . . . . . . . . . . . .
Contribution margin per aircraft . . . . . . . . .

Notice, January and February have the same net operating loss. This occurs because one
aircraft was sold in each month and, as previously mentioned, the selling price per aircraft, variable cost per aircraft, and total monthly fixed expenses remain constant.

Chapter 6
Absorption Costing Income Statement
As we begin the absorption costing portion of the example, remember that the only reason absorption costing income differs from variable costing is that the methods account
for fixed manufacturing overhead differently. Under absorption costing, fixed manufacturing overhead is included in product costs. In variable costing, fixed manufacturing
overhead is not included in product costs and instead is treated as a period expense just
like selling and administrative expenses.
The first step in preparing Weber’s absorption costing income statements for January,
February, and March is to determine the company’s unit product costs for each month as
follows1:

$60,000
17,500
$42,500
Notice that in each month, Weber’s fixed manufacturing overhead cost of $70,000 is
divided by the number of units produced to determine the fixed manufacturing overhead
cost per unit.
Given these unit product costs, the company’s absorption costing net operating
income in each month would be determined as shown in Exhibit 6–3.
The sales for all three months in Exhibit 6–3 are the same as the sales shown in the
variable costing income statements. The January cost of goods sold consists of one unit
produced during January at a cost of $95,000 according to the absorption costing system. The February cost of goods sold consists of one unit produced during February at
a cost of $60,000 according to the absorption costing system. The March cost of goods
sold ($230,000) consists of one unit produced during February at an absorption cost
of $60,000 plus four units produced in March with a total absorption cost of $170,000
(5 4 units produced 3 $42,500 per unit). The selling and administrative expenses equal
the amounts reported in the variable costing income statements; however they are reported
as one amount rather than being separated into variable and fixed components.

For simplicity, we assume in this section that an actual costing system is used in which actual costs
are spread over the units produced during the period. If a predetermined overhead rate were used, the
analysis would be similar, but more complex.
Variable Costing and Segment Reporting: Tools for Management
239
Note that even though sales were exactly the same in January and February and the
cost structure did not change, net operating income was $35,000 higher in February than
in January under absorption costing. This occurs because one aircraft produced in February is not sold until March. This aircraft has $35,000 of fixed manufacturing overhead
attached to it that was incurred in February, but will not be recorded as part of cost of
goods sold until March.
Contrasting the variable costing and absorption costing income statements in Exhibits
6–2 and 6–3, note that net operating income is the same in January under variable costing
and absorption costing, but differs in the other two months. We will discuss this in some
depth shortly. Also note that the format of the variable costing income statement differs
from the absorption costing income statement. An absorption costing income statement
categorizes costs by function—manufacturing versus selling and administrative. All of
the manufacturing costs flow through the absorption costing cost of goods sold and all of
the selling and administrative expenses are listed separately as period expenses. In contrast, in the contribution approach, costs are categorized according to how they behave.
All of the variable expenses are listed together and all of the fixed expenses are listed
together. The variable expenses category includes manufacturing costs (i.e., variable cost
of goods sold) as well as selling and administrative expenses. The fixed expenses category also includes both manufacturing costs and selling and administrative expenses.
THE BEHAVIORAL SIDE OF CALCULATING UNIT PRODUCT COSTS
IN BUSINESS
Andreas STIHL, a manufacturer of chain saws and other landscaping products, asked its U.S. subsidiary, STIHL Inc., to replace its absorption costing income statements with the variable costing
approach. From a computer systems standpoint, the change was not disruptive because STIHL
used an enterprise system called SAP that accommodates both absorption and variable costing.
However, from a behavioral standpoint, STIHL felt the change could be very disruptive. For example, STIHL’s senior managers were keenly aware that the variable costing approach reported lower
unit product costs than the absorption costing approach. Given this reality, the sales force might be
inclined to erroneously conclude that each product had magically become more profitable, thereby
justifying ill-advised price reductions. Because of behavioral concerns such as this, STIHL worked
hard to teach its employees how to interpret a variable costing income statement.

Reconciliation of Variable Costing with Absorption Costing Income
As noted earlier, variable costing and absorption costing net operating incomes may not
be the same. In the case of Weber Light Aircraft, the net operating incomes are the same
in January, but differ in the other two months. These differences occur because under
absorption costing some fixed manufacturing overhead is capitalized in inventories (i.e.,
included in product costs) rather than being immediately expensed on the income statement. If inventories increase during a period, under absorption costing some of the fixed
manufacturing overhead of the current period will be deferred in ending inventories.
For example, in February two aircraft were produced and each carried with it $35,000
(5 $70,000 4 2 aircraft produced) in fixed manufacturing overhead. Since only one aircraft was sold, $35,000 of this fixed manufacturing overhead was on February’s absorption costing income statement as part of cost of goods sold, but $35,000 would have been
on the balance sheet as part of finished goods inventories. In contrast, under variable costing all of the $70,000 of fixed manufacturing overhead appeared on the February income

240
Chapter 6
statement as a period expense. Consequently, net operating income was higher under
absorption costing than under variable costing by $35,000 in February. This was reversed
in March when four units were produced, but five were sold. In March, under absorption
costing $105,000 of fixed manufacturing overhead was included in cost of goods sold
($35,000 for the unit produced in February and sold in March plus $17,500 for each of
the four units produced and sold in March), but only $70,000 was recognized as a period
expense under variable costing. Hence, the net operating income in March was $35,000
lower under absorption costing than under variable costing.
In general, when the units produced exceed unit sales and hence inventories increase,
net operating income is higher under absorption costing than under variable costing. This
occurs because some of the fixed manufacturing overhead of the period is deferred in
inventories under absorption costing. In contrast, when unit sales exceed the units produced and hence inventories decrease, net operating income is lower under absorption
costing than under variable costing. This occurs because some of the fixed manufacturing overhead of previous periods is released from inventories under absorption costing.
When the units produced and unit sales are equal, no change in inventories occurs and
absorption costing and variable costing net operating incomes are the same.2
Variable costing and absorption costing net operating incomes can be reconciled by
determining how much fixed manufacturing overhead was deferred in, or released from,
inventories during the period:

These general statements about the relation between variable costing and absorption costing net operating income assume LIFO is used to value inventories. Even when LIFO is not used, the general statements tend to be correct. Although U.S. GAAP allows LIFO and FIFO inventory flow assumptions,
International Financial Reporting Standards do not allow a LIFO inventory flow assumption.

Net operating income is lower under absorption costing because fixed manufacturing
overhead cost is released from inventory under absorption costing as inventories

Again note that the difference between variable costing net operating income and absorption costing net operating income is entirely due to the amount of fixed manufacturing
overhead that is deferred in, or released from, inventories during the period under absorption costing. Changes in inventories affect absorption costing net operating income—they
do not affect variable costing net operating income, providing that variable manufacturing costs per unit are stable.
The reasons for differences between variable and absorption costing net operating
incomes are summarized in Exhibit 6–5. When the units produced equal the units sold, as
in January for Weber Light Aircraft, absorption costing net operating income will equal
variable costing net operating income. This occurs because when production equals sales,
all of the fixed manufacturing overhead incurred in the current period flows through to
the income statement under both methods. For companies that use Lean Production, the
number of units produced tends to equal the number of units sold. This occurs because
goods are produced in response to customer orders, thereby eliminating finished goods
inventories and reducing work in process inventory to almost nothing. So, when a company uses Lean Production differences in variable costing and absorption costing net
operating income will largely disappear.
When the units produced exceed the units sold, absorption costing net operating
income will exceed variable costing net operating income. This occurs because inventories have increased; therefore, under absorption costing some of the fixed manufacturing
overhead incurred in the current period is deferred in ending inventories on the balance
sheet, whereas under variable costing all of the fixed manufacturing overhead incurred
in the current period flows through to the income statement. In contrast, when the units
produced are less than the units sold, absorption costing net operating income will be
less than variable costing net operating income. This occurs because inventories have
decreased; therefore, under absorption costing fixed manufacturing overhead that had
been deferred in inventories during a prior period flows through to the current period’s
income statement together with all of the fixed manufacturing overhead incurred during
the current period. Under variable costing, just the fixed manufacturing overhead of the
current period flows through to the income statement.

IN BUSINESS
LEAN MANUFACTURING SHRINKS INVENTORIES
Conmed, a surgical device maker in Utica, New York, switched to lean manufacturing by replacing its assembly lines with U-shaped production cells. It also started producing only enough units
to satisfy customer demand rather than producing as many units as possible and storing them in
warehouses. The company calculated that its customers use one of its disposable surgical devices
every 90 seconds, so that is precisely how often it produces a new unit. Its assembly area for
fluid-injection devices used to occupy 3,300 square feet of space and contained $93,000 worth
of parts. Now the company produces its fluid-injection devices in 660 square feet of space while
maintaining only $6,000 of parts inventory.
When Conmed adopted lean manufacturing, it substantially reduced its finished goods inventories. What impact do you think this initial reduction in inventories may have had on net operating
income? Why?

Advantages of Variable Costing and the Contribution Approach
Variable costing, together with the contribution approach, offers appealing advantages
for internal reports. This section discusses three of those advantages.

CVP analysis requires that we break costs down into their fixed and variable components.
Because variable costing income statements categorize costs as fixed and variable, it is
much easier to use this income statement format to perform CVP analysis than attempting to use the absorption costing format, which mixes together fixed and variable costs.
Moreover, absorption costing net operating income may or may not agree with the
results of CVP analysis. For example, let’s suppose that you are interested in computing
the sales that would be necessary to generate a target profit of $235,000 at Weber Light
Aircraft. A CVP analysis based on the January variable costing income statement from
Exhibit 6–2 would proceed as follows:
Sales (a) . . . . . . . . . . . . . . . . . . . . . . . . . . .
Contribution margin (b) . . . . . . . . . . . . . . .
Contribution margin ratio (b) 4 (a) . . . . . . .
Total fixed expenses . . . . . . . . . . . . . . . . .
$100,000
$65,000
65%
$90,000
Target profit 1 Fixed expenses
Dollar sales to attain target profit 5 _________________________
CM ratio
$235,000 1 $90,000
5 _________________ 5 $500,000
0.65
Thus, a CVP analysis based on the January variable costing income statement predicts
that the net operating income would be $235,000 when sales are $500,000. And indeed,
the net operating income under variable costing is $235,000 when the sales are $500,000
Variable Costing and Segment Reporting: Tools for Management
in March. However, the net operating income under absorption costing is not $235,000
in March, even though the sales are $500,000. Why is this? The reason is that under
absorption costing, net operating income can be distorted by changes in inventories. In
March, inventories decreased, so some of the fixed manufacturing overhead that had been
deferred in February’s ending inventories was released to the March income statement,
resulting in a net operating income that is $35,000 lower than the $235,000 predicted by
CVP analysis. If inventories had increased in March, the opposite would have occurred—
the absorption costing net operating income would have been higher than the $235,000
predicted by CVP analysis.
Explaining Changes in Net Operating Income
The variable costing income statements in Exhibit 6–2 are clear and easy to understand.
All other things the same, when sales go up, net operating income goes up. When sales go
down, net operating income goes down. When sales are constant, net operating income is
constant. The number of units produced does not affect net operating income.
Absorption costing income statements can be confusing and are easily misinterpreted. Look again at the absorption costing income statements in Exhibit 6–3; a manager might wonder why net operating income went up from January to February even
though sales were exactly the same. Was it a result of lower selling costs, more efficient
operations, or was it some other factor? In fact, it was simply because the number of
units produced exceeded the number of units sold in February and so some of the fixed
manufacturing overhead costs were deferred in inventories in that month. These costs
have not gone away—they will eventually flow through to the income statement in a later
period when inventories go down. There is no way to tell this from the absorption costing
income statements.
To avoid mistakes when absorption costing is used, readers of financial statements
should be alert to changes in inventory levels. Under absorption costing, if inventories
increase, fixed manufacturing overhead costs are deferred in inventories, which in turn
increases net operating income. If inventories decrease, fixed manufacturing overhead
costs are released from inventories, which in turn decreases net operating income. Thus,
when absorption costing is used, fluctuations in net operating income can be caused by
changes in inventories as well as changes in sales.
Supporting Decision Making
The variable costing method correctly identifies the additional variable costs that will be
incurred to make one more unit. It also emphasizes the impact of fixed costs on profits.
The total amount of fixed manufacturing costs appears explicitly on the income statement, highlighting that the whole amount of fixed manufacturing costs must be covered
for the company to be truly profitable. In the Weber Light Aircraft example, the variable costing income statements correctly report that the cost of producing another unit is
$25,000 and they explicitly recognize that $70,000 of fixed manufactured overhead must
be covered to earn a profit.
Under absorption costing, fixed manufacturing overhead costs appear to be variable
with respect to the number of units sold, but they are not. For example, in January, the
absorption unit product cost at Weber Light Aircraft is $95,000, but the variable portion
of this cost is only $25,000. The fixed overhead costs of $70,000 are commingled with
variable production costs, thereby obscuring the impact of fixed overhead costs on profits. Because absorption unit product costs are stated on a per unit basis, managers may
mistakenly believe that if another unit is produced, it will cost the company $95,000.
But of course it would not. The cost of producing another unit would be only $25,000.
Misinterpreting absorption unit product costs as variable can lead to many problems,
including inappropriate pricing decisions and decisions to drop products that are in
fact profitable.

Chapter 6
Segmented Income Statements and the Contribution Approach
LO6–4
Prepare a segmented income
statement that differentiates
traceable fixed costs from
common fixed costs and use it
to make decisions.
In the remainder of the chapter, we’ll learn how to use the contribution approach to construct income statements for business segments. These segmented income statements are
useful for analyzing the profitability of segments, making decisions, and measuring the
performance of segment managers.
Traceable and Common Fixed Costs and the Segment Margin
You need to understand three new terms to prepare segmented income statements using
the contribution approach—traceable fixed cost, common fixed cost, and segment margin.
A traceable fixed cost of a segment is a fixed cost that is incurred because of the
existence of the segment—if the segment had never existed, the fixed cost would not
have been incurred; and if the segment were eliminated, the fixed cost would disappear.
Examples of traceable fixed costs include the following:
•
•
•
The salary of the Fritos product manager at PepsiCo is a traceable fixed cost of the
Fritos business segment of PepsiCo.
The maintenance cost for the building in which Boeing 747s are assembled is a
traceable fixed cost of the 747 business segment of Boeing.
The liability insurance at Disney World is a traceable fixed cost of the Disney World
business segment of The Walt Disney Corporation.
A common fixed cost is a fixed cost that supports the operations of more than one
segment, but is not traceable in whole or in part to any one segment. Even if a segment
were entirely eliminated, there would be no change in a true common fixed cost. For
example:
•
•
•
The salary of the CEO of General Motors is a common fixed cost of the various
divisions of General Motors.
The cost of heating a Safeway or Kroger grocery store is a common fixed cost of the
store’s various departments—groceries, produce, bakery, meat, and so forth.
The cost of the receptionist’s salary at an office shared by a number of doctors is a
common fixed cost of the doctors. The cost is traceable to the office, but not to individual doctors.
To prepare a segmented income statement, variable expenses are deducted from sales
to yield the contribution margin for the segment. The contribution margin tells us what
happens to profits as volume changes—holding a segment’s capacity and fixed costs constant. The contribution margin is especially useful in decisions involving temporary uses
of capacity such as special orders. These types of decisions often involve only variable
costs and revenues—the two components of contribution margin.
The segment margin is obtained by deducting the traceable fixed costs of a segment from the segment’s contribution margin. It represents the margin available after
a segment has covered all of its own costs. The segment margin is the best gauge of the
long-run profitability of a segment because it includes only those costs that are caused by
the segment. If a segment can’t cover its own costs, then that segment probably should be
dropped (unless it has important side effects on other segments). Notice, common fixed
costs are not allocated to segments.
From a decision-making point of view, the segment margin is most useful in major
decisions that affect capacity such as dropping a segment. By contrast, as we noted earlier, the contribution margin is most useful in decisions involving short-run changes in
volume, such as pricing special orders that involve temporary use of existing capacity.
Variable Costing and Segment Reporting: Tools for Management
HAS THE INTERNET KILLED CATALOGS?
Smith & Hawken, an outdoor-accessories retailer, has experienced growing Internet sales and
declining catalog sales. These trends seem consistent with conventional wisdom, which suggests
that the Internet will make catalogs obsolete. Yet, Smith & Hawken, like many retailers with growing Internet sales, has no plans to discontinue its catalogs. In fact, the total number of catalogs
mailed in the United States by all companies has jumped from 16.6 billion in 2002 to 19.2 billion
in 2005. Why?
Catalog shoppers and Internet shoppers are not independent customer segments. Catalog
shoppers frequently choose to complete their sales transactions online rather than placing telephone orders. This explains why catalogs remain a compelling marketing medium even though
catalog sales are declining for many companies. If retailers separately analyze catalog sales and
Internet sales, they may discontinue the catalogs segment while overlooking the adverse impact of
this decision on Internet segment margins.

Identifying Traceable Fixed Costs
The distinction between traceable and common fixed costs is crucial in segment reporting
because traceable fixed costs are charged to segments and common fixed costs are not. In
an actual situation, it is sometimes hard to determine whether a cost should be classified
as traceable or common.
The general guideline is to treat as traceable costs only those costs that would disappear over time if the segment itself disappeared. For example, if one division within a
company were sold or discontinued, it would no longer be necessary to pay that division
manager’s salary. Therefore the division manager’s salary would be classified as a traceable fixed cost of the division. On the other hand, the president of the company undoubtedly would continue to be paid even if one of many divisions was dropped. In fact, he
or she might even be paid more if dropping the division was a good idea. Therefore,
the president’s salary is common to the company’s divisions and should not be charged
to them.
When assigning costs to segments, the key point is to resist the temptation to allocate
costs (such as depreciation of corporate facilities) that are clearly common and that will
continue regardless of whether the segment exists or not. Any allocation of common costs
to segments reduces the value of the segment margin as a measure of long-run segment
profitability and segment performance.
Traceable Costs Can Become Common Costs
Fixed costs that are traceable to one segment may be a common cost of another segment.
For example, United Airlines might want a segmented income statement that shows the
segment margin for a particular flight from Chicago to Paris further broken down into
first-class, business-class, and economy-class segment margins. The airline must pay a
substantial landing fee at Charles DeGaulle airport in Paris. This fixed landing fee is a
traceable cost of the flight, but it is a common cost of the first-class, business-class, and
economy-class segments. Even if the first-class cabin is empty, the entire landing fee
must be paid. So the landing fee is not a traceable cost of the first-class cabin. But on the
other hand, paying the fee is necessary in order to have any first-class, business-class, or
economy-class passengers. So the landing fee is a common cost of these three classes.

IN BUSINESS
SEGMENT REPORTING AT THE VILAR PERFORMING ARTS CENTER
The Vilar Performing Arts Center is a 535-seat theater located in Beaver Creek, Colorado, that presents an unusually wide variety of performances categorized into six business segments—Family
Series, Broadway Series, Theatre/Comedy Series, Dance Series, Classical Series, and Concert
Series. The executive director of the Vilar, Kris Sabel, must decide which shows to book, what financial terms to offer to the artists, what contributions are likely from underwriters (i.e., donors), and
what prices to charge for tickets. He evaluates the profitability of the segments using segmented
income statements that include traceable costs (such as the costs of transporting, lodging, and
feeding the artists) and exclude common costs (such as the salaries of Kris and his staff, depreciation on the theater, and general marketing expenses).

Although the Classical Series sold an average of only 164 seats per show, its overall segment margin ($21,699) is positive thanks to $65,000 of underwriting revenues from donors. Had
common costs been allocated to the Classical Series, it may have appeared unprofitable and been
discontinued—resulting in fewer shows during the season; less diverse programming; disappointment among a small, but dedicated, number of fans; and lower overall income for the Vilar due to
the loss of its Classical Series segment margin.
Segmented Income Statements—An Example
ProphetMax, Inc., is a rapidly growing computer software company. Exhibit 6–6 shows
its variable costing income statement for the most recent month. As the company has
grown, its senior managers have asked for segmented income statements that could be
used to make decisions and evaluate managerial performance. ProphetMax’s controller
responded by creating examples of contribution format income statements segmented by
the company’s divisions, product lines, and sales channels. She created Exhibit 6–7 to
explain that ProphetMax’s profits can be segmented into its two divisions—the Business
Products Division and the Consumer Products Division. The Consumer Products Division’s profits can be further segmented into the Clip Art and Computer Games product
lines. Finally, the Computer Games product line’s profits (within the Consumer Products
Division) can be segmented into the Online and Retail Stores sales channels.
Levels of Segmented Income Statements
Exhibit 6–8, on page 248, contains the controller’s segmented income statements for
the segments depicted in Exhibit 6–7. The contribution format income statement for the
entire company appears at the very top of the exhibit under the column labeled Total
Company. Notice, the net operating income shown in this column ($13,500) is the same
as the net operating income shown in Exhibit 6–6. Immediately to the right of the Total
Company column are two columns—one for each of the two divisions. We can see that
the Business Products Division’s traceable fixed expenses are $90,000 and the Consumer

Products Division’s are $81,000. These $171,000 of traceable fixed expenses (as shown
in the Total Company column) plus the $85,500 of common fixed expenses not traceable
to individual divisions equals ProphetMax’s total fixed expenses ($256,500) as shown
in Exhibit 6–6. We can also see that the Business Products Division’s segment margin is
$60,000 and the Consumer Products Division’s is $39,000. These segment margins show
the company’s divisional managers how much each of their divisions is contributing to
the company’s profits.
The middle portion of Exhibit 6–8 further segments the Consumer Products Division
into its two product lines, Clip Art and Computer Games. The dual nature of some fixed
costs can be seen in this portion of the exhibit. Notice, in the top portion of Exhibit 6–8
when segments are defined as divisions, the Consumer Products Division has $81,000
in traceable fixed expenses. However, when we drill down to the product lines (in the

middle portion of the exhibit), only $70,000 of the $81,000 cost that was traceable to the
Consumer Products Division is traceable to the product lines. The other $11,000 becomes
a common fixed cost of the two product lines of the Consumer Products Division.
Why would $11,000 of traceable fixed costs become a common fixed cost when the
division is divided into product lines? The $11,000 is the monthly depreciation expense
on a machine that is used to encase products in tamper-proof packages for the consumer
market. The depreciation expense is a traceable cost of the Consumer Products Division
as a whole, but it is a common cost of the division’s two product lines. Even if one of
the product lines were discontinued entirely, the machine would still be used to wrap the
remaining products. Therefore, none of the depreciation expense can really be traced to
individual products. Conversely, the $70,000 traceable fixed cost can be traced to the
individual product lines because it consists of the costs of product-specific advertising. A
total of $30,000 was spent on advertising clip art and $40,000 was spent on advertising
computer programs.
The bottom portion of Exhibit 6–8 further segments the Computer Games product
line into two sales channels, Online Sales and Retail Stores. The dual nature of some
fixed costs can also be seen in this portion of the exhibit. In the middle portion of
Exhibit 6–8 when segments are defined as product lines, the Computer Games product
line has $40,000 in traceable fixed expenses. However, when we look at the sales channels in the bottom portion of the exhibit, only $25,000 of the $40,000 that was traceable
to Computer Games is traceable to the sales channels. The other $15,000 becomes a common fixed cost of the two sales channels for the Computer Games product line.
Segmented Income Statements—Decision Making and Break-Even Analysis
Once a company prepares contribution format segmented income statements, it can use
those statements to make decisions and perform break-even analysis.
Decision Making
Let’s refer again to the bottom portion of Exhibit 6–8 to illustrate how segmented income
statements support decision making. Notice that the Online Sales segment has a segment
margin of $48,000 and the Retail Stores segment has a segment margin of $(3,000). Let’s
assume that ProphetMax wants to know the profit impact of discontinuing the sale of
computer games through its Retail Stores sales channel. The company believes that online
sales of its computer games will increase 10% if it discontinues the Retail Stores sales
channel. It also believes that the Business Products Division and Clip Art product line will
be unaffected by this decision. How would you compute the profit impact of this decision?
The first step is to calculate the profit impact of the Retail Stores sales channel
disappearing. If this sales channel disappears, we assume its sales, variable expenses,
and traceable fixed expenses would all disappear. The quickest way to summarize these
financial impacts is to focus on the Retail Stores’ segment margin. In other words, if
the Retail Stores sales channel disappears, then its negative segment margin of $3,000
would also disappear. This would increase ProphetMax’s net operating income by
$3,000. The second step is to calculate the profit impact of increasing online sales of
computer games by 10%. To perform this calculation, we assume that the Online Sales
total traceable fixed expenses ($15,000) remain constant and its contribution margin
ratio remains constant at 63% (5 $63,000 4 $100,000). If online sales increase $10,000
(5 $100,000 3 10%), then the Online Sales segment’s contribution margin will increase
by $6,300 (5 $10,000 3 63%). The overall profit impact of discontinuing the Retail
Stores sales channel can be summarized as follows:

Chapter 6
Break-Even Analysis
In Chapter 5, we learned how to compute a companywide break-even point for a multiproduct company with no traceable fixed expenses. Now we are going to use the ProphetMax, Inc., data in Exhibit 6–8 to explain how to compute companywide and segment
break-even points for a company with traceable fixed expenses. The formula for computing a companywide break-even point is as follows:
Dollar sales for company ___________________________________________
Traceable fixed expenses 1 Common fixed expenses
5
to break even
Overall CM ratio
In the case of ProphetMax, we should begin by reviewing the information in the
Total Company column in the top portion of Exhibit 6–8. This column of data indicates
that ProphetMax’s total traceable fixed expenses are $171,000 and its total common
fixed expenses are $85,500. Furthermore, the company’s overall contribution margin of
$270,000 divided by its total sales of $500,000 equals its overall CM ratio of 0.54. Given
this information, ProphetMax’s companywide break-even point is computed as follows:
Dollar sales for company ___________________________________________
Traceable fixed expenses 1 Common fixed expenses

Overall CM ratio
$171,000
1
$85,500
5 _________________
0.54
$256,500
5 ________
0.54
5 $475,000
It is important to emphasize that this computation assumes a constant sales mix. In other
words, in the ProphetMax example, it assumes that 60% of the total sales ($300,000 4
$500,000) will always come from the Business Products Division and 40% of the total
sales ($200,000 4 $500,000) will always come from the Consumer Products Division.
To compute the break-even point for a business segment, the formula is as follows:
Dollar sales for a segment ____________________________
Segment traceable fixed expenses
5
to break even
Segment CM ratio
In the case of ProphetMax’s Business Products Division, we should begin by reviewing the information in the Business Products Division column in the top portion of
Exhibit 6–8. This column of data indicates that the Business Products Division’s traceable
fixed expenses are $90,000 and its CM ratio is 0.50 ($150,000 4 $300,000). Given this
information, the Business Products Division’s break-even point is computed as follows:
Segment traceable fixed expenses
Dollar sales for a segment ____________________________

5 $180,000
The same calculation can be performed for the Consumer Products Division using data
from the Consumer Products Division column in the top portion of Exhibit 6–8. Given
that the Consumer Products Division’s traceable fixed expenses are $81,000 and its CM
ratio is 0.60 ($120,000 4 $200,000), its break-even point is computed as follows:

Notice that the sum of the segment break-even sales figures of $315,000 ($180,000 1
$135,000) is less than the companywide break-even point of $475,000. This occurs
because the segment break-even calculations do not include the company’s common fixed
expenses. The exclusion of the company’s common fixed expenses can be verified by
preparing income statements based on each segment’s break-even dollar sales as follows:

When each segment achieves its break-even point, the company’s overall net operating
loss of $85,500 equals its common fixed expenses of $85,500. This reality can often lead
managers astray when making decisions. In an attempt to “cover the company’s common
fixed expenses,” managers will often allocate common fixed expenses to business segments when performing break-even calculations and making decisions. This is a mistake!
Allocating common fixed expenses to business segments artificially inflates each segment’s break-even point. This may cause managers to erroneously discontinue business
segments where the inflated break-even point appears unobtainable. The decision to
retain or discontinue a business segment should be based on the sales and expenses that
would disappear if the segment were dropped. Because common fixed expenses will persist even if a business segment is dropped, they should not be allocated to business segments when making decisions.
Segmented Income Statements—Common Mistakes
All of the costs attributable to a segment—and only those costs—should be assigned to
the segment. Unfortunately, companies often make mistakes when assigning costs to segments. They omit some costs, inappropriately assign traceable fixed costs, and arbitrarily
allocate common fixed costs.
Omission of Costs
The costs assigned to a segment should include all costs attributable to that segment from
the company’s entire value chain. All of these functions, from research and development,
through product design, manufacturing, marketing, distribution, and customer service,
are required to bring a product or service to the customer and generate revenues.
However, only manufacturing costs are included in product costs under absorption
costing, which is widely regarded as required for external financial reporting. To avoid
having to maintain two costing systems and to provide consistency between internal and
external reports, many companies also use absorption costing for their internal reports
such as segmented income statements. As a result, such companies omit from their profitability analysis part or all of the “upstream” costs in the value chain, which consist
of research and development and product design, and the “downstream” costs, which
consist of marketing, distribution, and customer service. Yet these nonmanufacturing
costs are just as essential in determining product profitability as are the manufacturing
costs. These upstream and downstream costs, which are usually included in selling and
251
252
Chapter 6
administrative expenses on absorption costing income statements, can represent half or
more of the total costs of an organization. If either the upstream or downstream costs are
omitted in profitability analysis, then the product is undercosted and management may
unwittingly develop and maintain products that in the long run result in losses.
Inappropriate Methods for Assigning Traceable Costs
among Segments
In addition to omitting costs, many companies do not correctly handle traceable fixed
expenses on segmented income statements. First, they do not trace fixed expenses to segments even when it is feasible to do so. Second, they use inappropriate allocation bases to
allocate traceable fixed expenses to segments.
Failure to Trace Costs Directly Costs that can be traced directly to a specific
segment should be charged directly to that segment and should not be allocated to other
segments. For example, the rent for a branch office of an insurance company should be
charged directly to the branch office rather than included in a companywide overhead
pool and then spread throughout the company.
Inappropriate Allocation Base Some companies use arbitrary allocation bases
to allocate costs to segments. For example, some companies allocate selling and administrative expenses on the basis of sales revenues. Thus, if a segment generates 20% of total
company sales, it would be allocated 20% of the company’s selling and administrative
expenses as its “fair share.” This same basic procedure is followed if cost of goods sold or
some other measure is used as the allocation base.
Costs should be allocated to segments for internal decision-making purposes only
when the allocation base actually drives the cost being allocated (or is very highly correlated with the real cost driver). For example, sales should be used to allocate selling and
administrative expenses only if a 10% increase in sales will result in a 10% increase in
selling and administrative expenses. To the extent that selling and administrative expenses
are not driven by sales volume, these expenses will be improperly allocated—with a disproportionately high percentage of the selling and administrative expenses assigned to
the segments with the largest sales.
Arbitrarily Dividing Common Costs among Segments
The third business practice that leads to distorted segment costs is the practice of assigning nontraceable costs to segments. For example, some companies allocate the common
costs of the corporate headquarters building to products on segment reports. However, in
a multiproduct company, no single product is likely to be responsible for any significant
amount of this cost. Even if a product were eliminated entirely, there would usually be
no significant effect on any of the costs of the corporate headquarters building. In short,
there is no cause-and-effect relation between the cost of the corporate headquarters building and the existence of any one product. As a consequence, any allocation of the cost of
the corporate headquarters building to the products must be arbitrary.
Common costs like the costs of the corporate headquarters building are necessary, of
course, to have a functioning organization. The practice of arbitrarily allocating common
costs to segments is often justified on the grounds that “someone” has to “cover the common costs.” While it is undeniably true that a company must cover its common costs to
earn a profit, arbitrarily allocating common costs to segments does not ensure that this will
happen. In fact, adding a share of common costs to the real costs of a segment may make an
otherwise profitable segment appear to be unprofitable. If a manager eliminates the apparently unprofitable segment, the real traceable costs of the segment will be saved, but its
revenues will be lost. And what happens to the common fixed costs that were allocated to
the segment? They don’t disappear; they are reallocated to the remaining segments of the
company. That makes all of the remaining segments appear to be less profitable—possibly
Variable Costing and Segment Reporting: Tools for Management
resulting in dropping other segments. The net effect will be to reduce the overall profits of
the company and make it even more difficult to “cover the common costs.”
Additionally, common fixed costs are not manageable by the manager to whom they
are arbitrarily allocated; they are the responsibility of higher-level managers. When common fixed costs are allocated to managers, they are held responsible for those costs even
though they cannot control them.
Income Statements—An External Reporting Perspective
Companywide Income Statements
Practically speaking, absorption costing is required for external reports according to U.S.
generally accepted accounting principles (GAAP).3 Furthermore, International Financial Reporting Standards (IFRS) explicitly require companies to use absorption costing.
Probably because of the cost and possible confusion of maintaining two separate costing
systems—one for external reporting and one for internal reporting—most companies use
absorption costing for their external and internal reports.
With all of the advantages of the contribution approach, you may wonder why the
absorption approach is used at all. While the answer is partly due to adhering to tradition, absorption costing is also attractive to many accountants and managers because they
believe it better matches costs with revenues. Advocates of absorption costing argue that
all manufacturing costs must be assigned to products in order to properly match the costs
of producing units of product with their revenues when they are sold. The fixed costs
of depreciation, taxes, insurance, supervisory salaries, and so on, are just as essential to
manufacturing products as are the variable costs.
Advocates of variable costing argue that fixed manufacturing costs are not really the
costs of any particular unit of product. These costs are incurred to have the capacity to
make products during a particular period and will be incurred even if nothing is made during the period. Moreover, whether a unit is made or not, the fixed manufacturing costs will
be exactly the same. Therefore, variable costing advocates argue that fixed manufacturing
costs are not part of the costs of producing a particular unit of product, and thus, the matching principle dictates that fixed manufacturing costs should be charged to the current period.
Segmented Financial Information
U.S. GAAP and IFRS require that publicly traded companies include segmented financial and other data in their annual reports and that the segmented reports prepared for
external users must use the same methods and definitions that the companies use in internal segmented reports that are prepared to aid in making operating decisions. This is a
very unusual stipulation because companies are not ordinarily required to report the same
data to external users that are used for internal decision-making purposes. This requirement creates incentives for publicly traded companies to avoid using the contribution
format for internal segmented reports. Segmented contribution format income statements
contain vital information that companies are often very reluctant to release to the public
(and hence competitors). In addition, this requirement creates problems in reconciling
internal and external reports.
3
The Financial Accounting Standards Board (FASB) has created a single source of authoritative nongovernmental U.S. generally accepted accounting principles (GAAP) called the FASB Accounting Standards Codification (FASB codification). Although the FASB codification does not explicitly disallow
variable costing, it does explicitly prohibit companies from excluding all manufacturing overhead costs
from product costs. It also provides an in-depth discussion of fixed overhead allocation to products,
thereby implying that absorption costing is required for external reports. Although some companies
expense significant elements of fixed manufacturing costs on their external reports, practically speaking,
U.S. GAAP requires absorption costing for external reports.

Summary
Variable and absorption costing are alternative methods of determining unit product costs. Under
variable costing, only those manufacturing costs that vary with output are treated as product costs.
This includes direct materials, variable overhead, and ordinarily direct labor. Fixed manufacturing
overhead is treated as a period cost and it is expensed on the income statement as incurred. By contrast, absorption costing treats fixed manufacturing overhead as a product cost, along with direct
materials, direct labor, and variable overhead. Under both costing methods, selling and administrative expenses are treated as period costs and they are expensed on the income statement as
incurred.
Because absorption costing treats fixed manufacturing overhead as a product cost, a portion
of fixed manufacturing overhead is assigned to each unit as it is produced. If units of product are
unsold at the end of a period, then the fixed manufacturing overhead cost attached to those units is
carried with them into the inventory account and deferred to a future period. When these units are
later sold, the fixed manufacturing overhead cost attached to them is released from the inventory
account and charged against income as part of cost of goods sold. Thus, under absorption costing, it is possible to defer a portion of the fixed manufacturing overhead cost from one period to a
future period through the inventory account.
Unfortunately, this shifting of fixed manufacturing overhead cost between periods can cause
erratic fluctuations in net operating income and can result in confusion and unwise decisions. To
guard against mistakes when they interpret income statement data, managers should be alert to
changes in inventory levels or unit product costs during the period.
Segmented income statements provide information for evaluating the profitability and performance of divisions, product lines, sales territories, and other segments of a company. Under the
contribution approach, variable costs and fixed costs are clearly distinguished from each other and
only those costs that are traceable to a segment are assigned to the segment. A cost is considered
Variable Costing and Segment Reporting: Tools for Management
traceable to a segment only if the cost is caused by the segment and could be avoided by eliminating the segment. Fixed common costs are not allocated to segments. The segment margin consists
of revenues, less variable expenses, less traceable fixed expenses of the segment.
The dollar sales required for a segment to break even is computed by dividing the segment’s
traceable fixed expenses by its contribution margin ratio. A company’s common fixed expenses
should not be allocated to segments when performing break-even calculations because they will
not change in response to segment-level decisions.

Redo the segment report, eliminating the allocation of common fixed expenses. Would the
firm be better off financially if the family law segment were dropped? (Note: Many of the
firm’s commercial law clients also use the firm for their family law requirements such as
drawing up wills.)
The firm’s advertising agency has proposed an ad campaign targeted at boosting the revenues
of the family law segment. The ad campaign would cost $20,000, and the advertising agency
claims that it would increase family law revenues by $100,000. The managing partner of
Frampton, Davis & Smythe believes this increase in business could be accommodated without
any increase in fixed expenses. Estimate the effect this ad campaign would have on the family
law segment margin and on the firm’s overall net operating income.

C41. The formula in this cell should be 5IF(C26,C27,C26*C361(C27-C26)*B36,C27*C36).
If your worksheet is operating properly, the net operating income under both absorption costing and variable costing should be $(34,000) for Year 2. That is, the loss in Year 2 is $34,000
under both systems. If you do not get these answers, find the errors in your worksheet and
correct them.
Why is the absorption costing net operating income now equal to the variable costing net
operating income in Year 2?

Is the net operating income under variable costing different in Year 1 and Year 2? Why or why
not? Explain the relation between the net operating income under absorption costing and variable costing in Year 1. Explain the relation between the net operating income under absorption
costing and variable costing in Year 2.
At the end of Year 1, the company’s board of directors set a target for Year 2 of net operating income of $500,000 under absorption costing. If this target is met, a hefty bonus would
be paid to the CEO of the company. Keeping everything else the same from part (2) above,
change the units produced in Year 2 to 50,000 units. Would this change result in a bonus being
paid to the CEO? Do you think this change would be in the best interests of the company?
What is likely to happen in Year 3 to the absorption costing net operating income if sales
remain constant at 12,000 units per year?

$150,000 is traceable to the East region, and the remaining $96,000 is a common fixed cost. The
company will continue to incur the total amount of its fixed manufacturing overhead costs as long
as it continues to produce any amount of its only product.

Answer each question independently based on the original data unless instructed otherwise. You do
not need to prepare a segmented income statement until question 13.
1. What is the unit product cost under variable costing?
2. What is the unit product cost under absorption costing?
3. What is the company’s total contribution margin under variable costing?
4. What is the company’s net operating income under variable costing?
5. What is the company’s total gross margin under absorption costing?
6. What is the company’s net operating income under absorption costing?
7. What is the amount of the difference between the variable costing and absorption costing net
operating incomes? What is the cause of this difference?
8. What is the company’s break-even point in unit sales? Is it above or below the actual sales
volume? Compare the break-even sales volume to your answer for question 6 and comment.
9. If the sales volumes in the East and West regions had been reversed, what would be the company’s overall break-even point in unit sales?
10. What would have been the company’s variable costing net operating income if it had produced
and sold 35,000 units? You do not need to perform any calculations to answer this question.
11. What would have been the company’s absorption costing net operating income if it had
produced and sold 35,000 units? You do not need to perform any calculations to answer this
question.
12. If the company produces 5,000 fewer units than it sells in its second year of operations, will
absorption costing net operating income be higher or lower than variable costing net operating income in Year 2? Why? No calculations are necessary.
13. Prepare a contribution format segmented income statement that includes a Total column and
columns for the East and West regions.
14. Diego is considering eliminating the West region because an internally generated report suggests the region’s total gross margin in the first year of operations was $50,000 less than its
traceable fixed selling and administrative expenses. Diego believes that if it drops the West
region, the East region’s sales will grow by 5% in Year 2. Using the contribution approach
for analyzing segment profitability and assuming all else remains constant in Year 2, what
would be the profit impact of dropping the West region in Year 2?
15. Assume the West region invests $30,000 in a new advertising campaign in Year 2 that
increases its unit sales by 20%. If all else remains constant, what would be the profit impact
of pursuing the advertising campaign?

Compute the companywide break-even point in dollar sales. Also, compute the break-even
point for the Chicago office and for the Minneapolis office. Is the companywide breakeven point greater than, less than, or equal to the sum of the Chicago and Minneapolis
break-even points? Why?
By how much would the company’s net operating income increase if Minneapolis increased
its sales by $75,000 per year? Assume no change in cost behavior patterns.
Refer to the original data. Assume that sales in Chicago increase by $50,000 next year and
that sales in Minneapolis remain unchanged. Assume no change in fixed costs.
a. Prepare a new segmented income statement for the company using the above format.
Show both amounts and percentages.
b. Observe from the income statement you have prepared that the contribution margin ratio
for Chicago has remained unchanged at 70% (the same as in the above data) but that the
segment margin ratio has changed. How do you explain the change in the segment margin ratio?

Management is disappointed with the company’s performance and is wondering what can be
done to improve profits. By examining sales and cost records, you have determined the following:
a. The company is divided into two sales territories—Northern and Southern. The Northern territory recorded $300,000 in sales and $156,000 in variable expenses during June; the remaining sales and variable expenses were recorded in the Southern territory. Fixed expenses of
$120,000 and $108,000 are traceable to the Northern and Southern territories, respectively.
The rest of the fixed expenses are common to the two territories.

Ms. Tyler is discouraged over the loss shown for the quarter, particularly because she had
planned to use the statement as support for a bank loan. Another friend, a CPA, insists that the company should be using absorption costing rather than variable costing and argues that if absorption

administrative expense is a 10% sales commission on all sales. The company’s total fixed expenses
include $72,000 of common fixed expenses that would continue to be incurred even if the Commercial or Residential segments are discontinued, $38,000 of fixed expenses that would be avoided
if the Residential segment is dropped, and $55,000 of fixed expenses that would be avoided if the

In the latter part of Year 2, a competitor went out of business and in the process dumped a
large number of units on the market. As a result, Starfax’s sales dropped by 20% during Year 2
even though production increased during the year. Management had expected sales to remain constant at 50,000 units; the increased production was designed to provide the company with a buffer
of protection against unexpected spurts in demand. By the start of Year 3, management could see
that inventory was excessive and that spurts in demand were unlikely. To reduce the excessive
inventories, Starfax cut back production during Year 3, as shown below:

Additional information about the company follows:
The company’s plant is highly automated. Variable manufacturing expenses (direct materials,
direct labor, and variable manufacturing overhead) total only $2 per unit, and fixed manufacturing overhead expenses total $480,000 per year.
Fixed manufacturing overhead costs are applied to units of product on the basis of each year’s
production. That is, a new fixed manufacturing overhead rate is computed each year.
Variable selling and administrative expenses were $1 per unit sold in each year. Fixed selling
and administrative expenses totaled $140,000 per year.
The company uses a FIFO inventory flow assumption.
Starfax’s management can’t understand why profits doubled during Year 2 when sales dropped by
20% and why a loss was incurred during Year 3 when sales recovered to previous levels.

Prepare a contribution format variable costing income statement for each year.
Refer to the absorption costing income statements above.
a. Compute the unit product cost in each year under absorption costing. (Show how much
of this cost is variable and how much is fixed.)
b. Reconcile the variable costing and absorption costing net operating income figures for
each year.
Refer again to the absorption costing income statements. Explain why net operating income
was higher in Year 2 than it was in Year 1 under the absorption approach, in light of the fact
that fewer units were sold in Year 2 than in Year 1.
Refer again to the absorption costing income statements. Explain why the company suffered a loss
in Year 3 but reported a profit in Year 1 although the same number of units was sold in each year.
a. Explain how operations would have differed in Year 2 and Year 3 if the company had
been using Lean Production, with the result that ending inventory was zero.
b. If Lean Production had been used during Year 2 and Year 3 and the predetermined overhead rate is based on 50,000 units per year, what would the company’s net operating
income (or loss) have been in each year under absorption costing? Explain the reason for
any differences between these income figures and the figures reported by the company in
the statements above.

The division can rent warehouse space to store up to 1,000 units. The minimum inventory
level that the division should carry is 50 units. Mr. Cavalas is aware that production must be at least
200 units per quarter in order to retain a nucleus of key employees. Maximum production capacity
is 1,500 units per quarter.
Demand has been soft, and the sales forecast for the last quarter is only 600 units. Due
to the nature of the division’s operations, fixed manufacturing overhead is a major element of
product cost.

Will the number of units scheduled for production affect the division’s reported income or
loss for the year? Explain.
Assume that the division is using absorption costing and that the divisional manager is given
an annual bonus based on divisional operating income. If Mr. Cavalas wants to maximize his
division’s operating income for the year, how many units should be scheduled for production

The following additional information is available about the company:
Only printing costs and sales commissions are variable; all other costs are fixed. The printing
costs (which include materials, labor, and variable overhead) are traceable to the three product
lines as shown in the statement above. Sales commissions are 10% of sales for any product.
b. The same equipment is used to produce all three books, so the equipment depreciation cost
has been allocated equally among the three product lines. An analysis of the company’s activities indicates that the equipment is used 30% of the time to produce cookbooks, 50% of the
time to produce travel guides, and 20% of the time to produce handy spellers.
c. The warehouse is used to store finished units of product, so the rental cost has been allocated
to the product lines on the basis of sales dollars. The warehouse rental cost is $3 per square
foot per year. The warehouse contains 48,000 square feet of space, of which 7,200 square feet
is used by the cookbook line, 24,000 square feet by the travel guide line, and 16,800 square
feet by the handy speller line.
d. The general sales cost above includes the salary of the sales manager and other sales costs not
traceable to any specific product line. This cost has been allocated to the product lines on the
basis of sales dollars.
e. The general administration cost and depreciation of office facilities both relate to administration of the company as a whole. These costs have been allocated equally to the three product
lines.

Appendix 6A: Super-Variable Costing
In the discussion of variable costing in this chapter we have assumed that direct labor and
a portion of manufacturing overhead are variable costs that should be attached to products.
However, these assumptions about cost behavior may not be true. For example, it may be
easier and more accurate to assume that all manufacturing overhead costs are fixed costs
because the variable portion of these costs is insignificant or too difficult to estimate. Furthermore, many companies’ labor costs (including direct and indirect labor) are more fixed
than variable due to labor regulations, labor contracts, or management policy. In countries such as France, Germany, Spain, and Japan, management often has little flexibility
in adjusting the labor force to changes in business activity. Even in countries such as the
United States and the United Kingdom, where management usually has greater latitude to
adjust the size of its labor force, many managers choose to view labor as a fixed cost. They
make this choice because the cost savings from terminating or laying off employees during a short-term business downturn may be swamped by the negative effects on employee
morale and by the costs of later finding and training suitable replacements. Moreover,
treating employees as variable costs subtly fosters the attitude that employees are expendable and replaceable like materials rather than unique, difficult-to-replace assets.
Super-variable costing is a variation on variable costing in which direct labor and
manufacturing overhead costs are considered to be fixed. Super-variable costing classifies all direct labor and manufacturing overhead costs as fixed period costs and only
direct materials as a variable product cost. To simplify, in this appendix we also assume
that selling and administrative expenses are entirely fixed.
Super-Variable Costing and Variable Costing—An Example
To illustrate the difference between treating direct labor as a fixed cost (as in supervariable costing) and treating direct labor as a variable cost (as in variable costing), we
will use a modified version of the Weber Light Aircraft example from the main body of
the chapter. Data concerning the company’s operations appear below:

The key thing to notice here is that direct labor is a fixed cost—$20,000 per month.
Also, notice that Weber Light Aircraft has no variable manufacturing overhead costs and
no variable selling and administrative expenses. For the months of January, February,
and March, the company’s selling price per aircraft, variable cost per aircraft, monthly
production in units, and total monthly fixed expenses never change. The only thing that
changes in this example is the number of units sold (January 5 2 units sold; February 5
1 unit sold; March 5 3 units sold).
We will first construct the company’s super-variable costing income statements for
January, February, and March. Then we will show how the company’s net operating
income would be determined for the same months using variable costing if it were incorrectly assumed that direct labor is a variable cost. As you’ll see, both income statements
rely on the contribution format.
Super-Variable Costing Income Statements
To prepare the company’s super-variable costing income statements for each month we follow four steps. First, we compute sales by multiplying the number of units sold by the selling
price per unit, which in this example is $100,000 per unit. Second, we compute the variable
cost of goods sold by multiplying the number of units sold by the unit product cost, which in
this example is the direct materials cost of $19,000 per unit. Third, we compute the contribution margin by subtracting the variable cost of goods sold from sales. Fourth, we compute
net operating income by subtracting all fixed expenses from the contribution margin.
Using these four steps, Weber’s super-variable costing income statements for each
month would appear as shown in Exhibit 6A–1. Notice that the only variable expense is
variable cost of goods sold, which is the $19,000 of direct materials per unit sold. For example, in March, the unit product cost of $19,000 is multiplied by three units sold to obtain
the variable cost of goods sold of $57,000. The total monthly fixed manufacturing expenses
of $94,000 include $20,000 of direct labor and $74,000 of fixed manufacturing overhead.

Variable Costing Income Statements
The variable costing income statements in this example differ from the super-variable
costing income statements in one important respect—we will assume that direct labor
is incorrectly classified as a variable cost and is included in unit product costs. Because
the monthly direct labor cost is $20,000 and two aircraft are produced each month, if
direct labor costs are included in unit product costs, then Weber Light Aircraft will assign

$29,000
Given these unit product cost figures, the company’s variable costing income statements would be computed as shown in Exhibit 6A–2. For example, in March, the unit
product cost of $29,000 is multiplied by three units sold to obtain the variable cost of
goods sold of $87,000. The total fixed manufacturing overhead of $74,000 and total fixed
selling and administrative expenses of $40,000 are both recorded as period expenses.
Reconciliation of Super-Variable Costing and Variable
Costing Income
The super-variable costing and variable costing net operating incomes are both $28,000 in
January. However, in February, the super-variable costing income is $10,000 lower than the
variable costing income and the opposite holds true in March. In other words, the supervariable costing income in March is $10,000 higher than the variable costing income.
Why do these two costing methods produce different net operating incomes? The
answer can be found in the accounting for direct labor costs. Super-variable costing treats
direct labor as a fixed period expense whereas variable costing treats direct labor as a variable product cost. In other words, super-variable costing records the entire direct labor
cost of $20,000 as an expense on each month’s income statement. Conversely, variable
costing assigns $10,000 of direct labor cost to each unit produced. The $10,000 assigned
to each unit produced remains in inventory on the balance sheet until the unit is sold—at
which point the $10,000 assigned to it is transferred to variable cost of goods sold on the
income statement. Given this background, the super-variable costing and variable costing
incomes for each month can be reconciled as follows:

In January, both costing methods report the same net operating income ($28,000).
This occurs because each method expenses $20,000 of direct labor in the income statement. In February, super-variable costing income is $10,000 less than variable costing
income. This difference arises because super-variable costing expenses $20,000 of direct
labor in the income statement, whereas variable costing expenses only $10,000 of direct
labor in the income statement ($10,000 per unit 3 1 unit sold) and defers $10,000 of
direct labor on the balance sheet ($10,000 per unit 3 1 unit produced but not sold). In
March, super-variable costing income is $10,000 greater than variable costing income.
This difference arises because super-variable costing expenses $20,000 of direct labor on
the income statement, whereas variable costing expenses $30,000 of direct labor on the
income statement ($10,000 per unit 3 3 unit sold). Notice that one of the units sold in
March was actually produced in February. Under variable costing, the $10,000 of direct
labor attached to the unit produced in February is released from inventory and included in
variable cost of goods sold for March.
In summary, the key issue considered in this appendix is how a company treats
direct labor costs. If a company treats direct labor as a variable cost, the cost system
may encourage managers to treat labor costs as an expense to be minimized when sales
decline and this may result in reduced morale and eventual problems when business picks
up. Second, in practice management may have little ability to adjust the direct labor force
even if they wanted to, resulting in a situation in which direct labor costs are in fact fixed.
In either case, treating direct labor costs as variable can lead to bad decisions. The supervariable costing approach overcomes this problem by treating labor costs as fixed costs.

LEARNING OBJECTIVES
After studying Chapter 7, you should be
able to:
Managers often understand that increasing the variety of raw material inputs
used in their products increases costs. For example, General Mills studied
its 50 varieties of Hamburger Helper and concluded that it could lower costs
by discontinuing half of them without alienating customers. Seagate studied
seven varieties of its computer hard drives and found that only 2% of their
parts could be shared by more than one hard drive. The engineers fixed the
problem by redesigning the hard drives so that they used more common
component parts. Instead of using 61 types of screws to make the hard
drives, the engineers reduced the number of screws needed to 19. Eventually all Seagate products were designed so that 75% of their component
parts were shared with other product lines.
Activity-based costing systems quantify the increase in costs, such as
procurement costs, material handling costs, and assembly costs that are
caused by inefficient product designs and other factors. ■

Activity-Based Costing: A Tool to Aid Decision Making
287
his chapter introduces the concept of activity-based costing which
has been embraced by a wide variety of organizations including Charles Schwab,
Citigroup, Lowe’s, Coca-Cola, J&B Wholesale, Fairchild Semiconductor,
Assan Aluminum, Sysco Foods, Fisher Scientific International, and
Peregrine Outfitters. Activity-based costing (ABC) is a costing method that is designed
to provide managers with cost information for strategic and other decisions that potentially affect capacity and therefore “fixed” as well as variable costs. Activity-based costing is ordinarily used as a supplement to, rather than as a replacement for, a company’s
usual costing system. Most organizations that use activity-based costing have two costing
systems—the official costing system that is used for preparing external financial reports
and the activity-based costing system that is used for internal decision making and for
managing activities.
This chapter focuses primarily on ABC applications in manufacturing to provide a
contrast with the material presented in earlier chapters. More specifically, Chapters 3 and
4 focused on traditional absorption costing systems used by manufacturing companies
to calculate unit product costs for the purpose of valuing inventories and determining
cost of goods sold for external financial reports. In contrast, this chapter explains how
manufacturing companies can use activity-based costing rather than traditional methods
to calculate unit product costs for the purposes of managing overhead and making decisions. Chapter 6 had a similar purpose. That chapter focused on how to use variable costing to aid decisions that do not affect fixed costs. This chapter extends that idea to show
how activity-based costing can be used to aid decisions that potentially affect fixed costs
as well as variable costs.
T
Activity-Based Costing: An Overview
As stated above, traditional absorption costing is designed to provide data for external
financial reports. In contrast, activity-based costing is designed to be used for internal decision making. As a consequence, activity-based costing differs from traditional
absorption costing in three ways. In activity-based costing:
1. Nonmanufacturing as well as manufacturing costs may be assigned to products, but
only on a cause-and-effect basis.
2. Some manufacturing costs may be excluded from product costs.
3. Numerous overhead cost pools are used, each of which is allocated to products and
other cost objects using its own unique measure of activity.
Each of these departures from traditional absorption costing will be discussed in turn.
Nonmanufacturing Costs and Activity-Based Costing
In traditional absorption costing, manufacturing costs are assigned to products and nonmanufacturing costs are not assigned to products. Conversely, in activity-based costing,
we recognize that many nonmanufacturing costs relate to selling, distributing, and servicing specific products. Thus, ABC includes manufacturing and nonmanufacturing costs
when calculating the entire cost of a product rather than just its manufacturing cost.
There are two types of nonmanufacturing costs that ABC systems assign to products.
First, ABC systems trace all direct nonmanufacturing costs to products. Commissions
paid to salespersons, shipping costs, and warranty repair costs are examples of nonmanufacturing costs that can be directly traced to individual products. Second, ABC systems
allocate indirect nonmanufacturing costs to products whenever the products have presumably caused the costs to be incurred. In fact, in this chapter, we emphasize this point
by expanding the definition of overhead to include all indirect costs—manufacturing and
nonmanufacturing.

Understand activity-based
costing and how it differs from
a traditional costing system.
288
Chapter 7
In summary, ABC product cost calculations include all direct costs that can be
traced to products and all indirect costs that are caused by products. The need to distinguish between manufacturing and nonmanufacturing costs disappears—which is very
different from earlier chapters that focused solely on determining the manufacturing
cost of a product.
Manufacturing Costs and Activity-Based Costing
In traditional absorption costing systems, all manufacturing costs are assigned to
products—even manufacturing costs that are not caused by the products. For example, in
Chapter 3 we learned that a predetermined plantwide overhead rate is computed by dividing all budgeted manufacturing overhead costs by a measure of budgeted activity such as
direct labor-hours. This approach spreads all manufacturing overhead costs across products based on each product’s direct labor-hour usage. In contrast, activity-based costing
systems purposely do not assign two types of manufacturing overhead costs to products.
Manufacturing overhead includes costs such as the factory security guard’s wages,
the plant controller’s salary, and the cost of supplies used by the plant manager’s secretary. These types of costs are assigned to products in a traditional absorption costing system even though they are totally unaffected by which products are made during a period.
In contrast, activity-based costing systems do not arbitrarily assign these types of costs,
which are called organization-sustaining costs, to products. Activity-based costing treats
these types of costs as period expenses rather than product costs.
Additionally, in a traditional absorption costing system, the costs of unused, or idle,
capacity are assigned to products. If the budgeted level of activity declines, the overhead
rate and unit product costs increase as the increasing costs of idle capacity are spread over
a smaller base. In contrast, in activity-based costing, products are only charged for the
costs of the capacity they use—not for the costs of capacity they don’t use. This provides
more stable unit product costs and is consistent with the goal of assigning to products
only the costs of the resources that they use.1
Exhibit 7–1 summarizies the two departures from traditional absorption costing that
we have discussed thus far. The top portion of the exhibit shows that traditional absorption
costing treats all manufacturing costs as product costs and all nonmanufacturing costs as
period costs. The bottom portion of the exhibit shows that activity-based costing expands
the definition of overhead to include all indirect costs—manufacturing and nonmanufacturing. The overhead costs that are caused by products are allocated to them, whereas any
overhead costs that are not caused by products are treated as period costs. It also shows
that ABC treats direct nonmanufacturing costs as product costs rather than period costs.
Now we turn our attention to the third and final difference between traditional absorption costing and activity-based costing.
Cost Pools, Allocation Bases, and Activity-Based Costing
Throughout the 19th century and most of the 20th century, cost system designs were
simple and satisfactory. Typically, either one plantwide overhead cost pool or a number
of departmental overhead cost pools were used to assign overhead costs to products. The
plantwide and departmental approaches always had one thing in common—they relied
on allocation bases such as direct labor-hours and machine-hours for allocating overhead
costs to products. In the labor-intensive production processes of many years ago, direct
labor was the most common choice for an overhead allocation base because it represented a large component of product costs, direct labor-hours were closely tracked, and
1
Appendix 3B discusses how the costs of idle capacity can be accounted for as a period cost in an
income statement. This treatment highlights the cost of idle capacity rather than burying it in inventory
and cost of goods sold. The procedures laid out in this chapter for activity-based costing have the same
end effect.

many managers believed that direct labor-hours, the total volume of units produced, and
overhead costs were highly correlated. (Three variables, such as direct labor-hours, the
total volume of units produced, and overhead costs, are highly correlated if they tend to
move together.) Given that most companies at the time were producing a very limited
variety of products that required similar resources to produce, allocation bases such as
direct labor-hours, or even machine-hours, worked fine because, in fact, there was probably little difference in the overhead costs attributable to different products.
Then conditions began to change. As a percentage of total cost, direct labor began
declining and overhead began increasing. Many tasks previously done by direct laborers
were being performed by automated equipment—a component of overhead. Companies
began creating new products and services at an ever-accelerating rate that differed in volume, batch size, and complexity. Managing and sustaining this product diversity required
investing in many more overhead resources, such as production schedulers and product
design engineers, that had no obvious connection to direct labor-hours or machine-hours.
In this new environment, continuing to rely exclusively on a limited number of overhead
cost pools and traditional allocation bases posed the risk that reported unit product costs
would be distorted and, therefore, misleading when used for decision-making purposes.

Chapter 7
Activity-based costing, thanks to advances in technology that make more complex
cost systems feasible, provides an alternative to the traditional plantwide and departmental approaches to defining cost pools and selecting allocation bases. The activity-based
approach has appeal in today’s business environment because it uses more cost pools and
unique measures of activity to better understand the costs of managing and sustaining
product diversity.
In activity-based costing, an activity is any event that causes the consumption of
overhead resources. An activity cost pool is a “bucket” in which costs are accumulated
that relate to a single activity measure in the ABC system. An activity measure is an
allocation base in an activity-based costing system. The term cost driver is also used to
refer to an activity measure because the activity measure should “drive” the cost being
allocated. The two most common types of activity measures are transaction drivers and
duration drivers. Transaction drivers are simple counts of the number of times an activity occurs, such as the number of bills sent out to customers. Duration drivers measure
the amount of time required to perform an activity, such as the time spent preparing
individual bills for customers. In general, duration drivers are more accurate measures of
resource consumption than transaction drivers, but they take more effort to record. For
that reason, transaction drivers are often used in practice.
IN BUSINESS
A CRITICAL PERSPECTIVE OF ABC
Marconi is a Portuguese telecommunications company that encountered problems with its ABC
system. The company’s production managers felt that 23% of the costs included in the system were
common costs that should not be allocated to products and that allocating these costs to products
was not only inaccurate, but also irrelevant to their operational cost reduction efforts. Furthermore,
Marconi’s front-line workers resisted the ABC system because they felt it might be used to weaken
their autonomy and to justify downsizing, outsourcing, and work intensification. They believed that
ABC created a “turkeys queuing for Christmas syndrome” because they were expected to volunteer
information to help create a cost system that could eventually lead to their demise. These two complications created a third problem—the data necessary to build the ABC cost model was provided
by disgruntled and distrustful employees. Consequently, the accuracy of the data was questionable
at best. In short, Marconi’s experiences illustrate some of the challenges that complicate real-world
ABC implementations.

Traditional cost systems rely exclusively on allocation bases that are driven by the volume of production. On the other hand, activity-based costing defines five levels of activity—
unit-level, batch-level, product-level, customer-level, and organization-sustaining—that
largely do not relate to the volume of units produced. The costs and corresponding activity
measures for unit-level activities do relate to the volume of units produced; however, the
remaining categories do not. These levels are described as follows:2
1. Unit-level activities are performed each time a unit is produced. The costs of unitlevel activities should be proportional to the number of units produced. For example,
providing power to run processing equipment would be a unit-level activity because
power tends to be consumed in proportion to the number of units produced.
2. Batch-level activities are performed each time a batch is handled or processed,
regardless of how many units are in the batch. For example, tasks such as placing

Activity-Based Costing: A Tool to Aid Decision Making
291
purchase orders, setting up equipment, and arranging for shipments to customers
are batch-level activities. They are incurred once for each batch (or customer order).
Costs at the batch level depend on the number of batches processed rather than on
the number of units produced, the number of units sold, or other measures of volume. For example, the cost of setting up a machine for batch processing is the same
regardless of whether the batch contains one or thousands of items.
3. Product-level activities relate to specific products and typically must be carried out
regardless of how many batches are run or units of product are produced or sold. For
example, activities such as designing a product, advertising a product, and maintaining a product manager and staff are all product-level activities.
4. Customer-level activities relate to specific customers and include activities such as
sales calls, catalog mailings, and general technical support that are not tied to any
specific product.
5. Organization-sustaining activities are carried out regardless of which customers
are served, which products are produced, how many batches are run, or how many
units are made. This category includes activities such as heating the factory, cleaning executive offices, providing a computer network, arranging for loans, preparing
annual reports to shareholders, and so on.
Many companies throughout the world continue to base overhead allocations on
direct labor-hours or machine-hours. In situations where overhead costs and direct laborhours are highly correlated or in situations where the goal of the overhead allocation
process is to prepare external financial reports, this practice makes sense. However, if
plantwide overhead costs do not move in tandem with plantwide direct labor-hours or
machine-hours, product costs will be distorted—with the potential of distorting decisions
made within the company.
DINING IN THE CANYON
Western River Expeditions (www.westernriver.com) runs river rafting trips on the Colorado, Green,
and Salmon rivers. One of its most popular trips is a six-day trip down the Grand Canyon, which
features famous rapids such as Crystal and Lava Falls as well as the awesome scenery accessible
only from the bottom of the Grand Canyon. The company runs trips of one or two rafts, each of
which carries two guides and up to 18 guests. The company provides all meals on the trip, which
are prepared by the guides.
In terms of the hierarchy of activities, a guest can be considered as a unit and a raft as a batch.
In that context, the wages paid to the guides are a batch-level cost because each raft requires two
guides regardless of the number of guests in the raft. Each guest is given a mug to use during the
trip and to take home at the end of the trip as a souvenir. The cost of the mug is a unit-level cost
because the number of mugs given away is strictly proportional to the number of guests on a trip.
What about the costs of food served to guests and guides—is this a unit-level cost, a batchlevel cost, a product-level cost, or an organization-sustaining cost? At first glance, it might be
thought that food costs are a unit-level cost—the greater the number of guests, the higher the food
costs. However, that is not quite correct. Standard menus have been created for each day of the
trip. For example, the first night’s menu might consist of shrimp cocktail, steak, cornbread, salad,
and cheesecake. The day before a trip begins, all of the food needed for the trip is taken from the
central warehouse and packed in modular containers. It isn’t practical to finely adjust the amount of
food for the actual number of guests planned to be on a trip—most of the food comes prepackaged
in large lots. For example, the shrimp cocktail menu may call for two large bags of frozen shrimp
per raft and that many bags will be packed regardless of how many guests are expected on the
raft. Consequently, the costs of food are not a unit-level cost that varies with the number of guests
actually on a trip. Instead, the costs of food are a batch-level cost.

Chapter 7
Designing an Activity-Based Costing (ABC) System
There are three essential characteristics of a successful activity-based costing implementation. First, top managers must strongly support the ABC implementation because their
leadership is instrumental in properly motivating all employees to embrace the need to
change. Second, top managers should ensure that ABC data is linked to how people are
evaluated and rewarded. If employees continue to be evaluated and rewarded using traditional (non-ABC) cost data, they will quickly get the message that ABC is not important and they will abandon it. Third, a cross-functional team should be created to design
and implement the ABC system. The team should include representatives from each area
that will use ABC data, such as the marketing, production, engineering, and accounting
departments. These cross-functional employees possess intimate knowledge of many parts
of an organization’s operations that is necessary for designing an effective ABC system.
Furthermore, tapping the knowledge of cross-functional managers lessens their resistance to ABC because they feel included in the implementation process. Time after time,
when accountants have attempted to implement an ABC system on their own without
top-management support and cross-functional involvement, the results have been ignored.

IMPLEMENTING ACTIVITY-BASED COSTING IN CHINA
Xu Ji Electric Company is publicly traded on China’s Shen Zhen Stock Exchange. From 2001–2003,
it successfully implemented an activity-based costing (ABC) system because top-level managers
continuously supported the new system—particularly during a challenging phase when the ABC
software encountered problems. The ABC adoption was also aided by Xu Ji’s decision to drive the
implementation using a top-down approach, which is aligned with the company’s cultural norm of
deferring to and supporting the hierarchical chain of command.
Xu Ji’s experience is similar to Western ABC implementations that have consistently recognized the necessity of top-level management support. However, contrary to Xu Ji’s experience,
many Western managers do not readily support the top-down implementation of new management
innovations in their organizations. They prefer to be involved in the decision-making processes that
introduce change into their organizations.

MANAGERIAL
ACCOUNTING IN ACTION
THE ISSUE
Classic Brass, Inc., makes two main product lines for luxury yachts—standard stanchions
and custom compass housings. The president of the company, John Towers, recently
attended a management conference at which activity-based costing was discussed. Following the conference, he called a meeting of the company’s top managers to discuss
what he had learned. Attending the meeting were production manager Susan Richter, the
marketing manager Tom Olafson, and the accounting manager Mary Goodman. He began
the conference by distributing the company’s income statement that Mary Goodman had
prepared a few hours earlier (see Exhibit 7–2):
John: Well, it’s official. Our company has sunk into the red for the first time in its
history—a loss of $1,250.
Tom: I don’t know what else we can do! Given our successful efforts to grow sales of
the custom compass housings, I was expecting to see a boost to our bottom line, not
a net loss. Granted, we have been losing even more bids than usual for standard stanchions because of our recent price increase, but . . .
John: Do you think our prices for standard stanchions are too high?

Tom: No, I don’t think our prices are too high. I think our competitors’ prices are too
low. In fact, I’ll bet they are pricing below their cost.
Susan: Why would our competitors price below their cost?
Tom: They are out to grab market share.
Susan: What good is more market share if they are losing money on every unit sold?
John: I think Susan has a point. Mary, what is your take on this?
Mary: If our competitors are pricing standard stanchions below cost, shouldn’t they be
losing money rather than us? If our company is the one using accurate information to
make informed decisions while our competitors are supposedly clueless, then why is
our “bottom line” taking a beating? Unfortunately, I think we may be the ones relying on distorted cost data, not our competitors.
John: Based on what I heard at the conference that I just attended, I am inclined to
agree. One of the presentations at the conference dealt with activity-based costing.
As the speaker began describing the usual insights revealed by activity-based costing
systems, I was sitting in the audience getting an ill feeling in my stomach.
Mary: Honestly John, I have been claiming for years that our existing cost system is
okay for external reporting, but it is dangerous to use it for internal decision making.
It sounds like you are on board now, right?
John: Yes.
Mary: Well then, how about if all of you commit the time and energy to help me build a
fairly simple activity-based costing system that may shed some light on the problems
we are facing?
John: Let’s do it. I want each of you to appoint one of your top people to a special
“ABC team” to investigate how we cost products.
Like most other ABC implementations, the ABC team decided that its new ABC system would supplement, rather than replace, the existing cost accounting system, which
would continue to be used for external financial reports. The new ABC system would be
used to prepare special reports for management decisions such as bidding on new business.
The accounting manager drew the chart appearing in Exhibit 7–3 to explain the general structure of the ABC model to her team members. Cost objects such as products generate activities. For example, a customer order for a custom compass housing requires the
activity of preparing a production order. Such an activity consumes resources. A production order uses a sheet of paper and takes time to fill out. And consumption of resources
causes costs. The greater the number of sheets used to fill out production orders and

the greater the amount of time devoted to filling out such orders, the greater the cost.
Activity-based costing attempts to trace through these relationships to identify how products and customers affect costs.
As in most other companies, the ABC team at Classic Brass felt that the company’s traditional cost accounting system adequately measured the direct materials and
direct labor costs of products because these costs are directly traced to products. Therefore, the ABC study would be concerned solely with the other costs of the company—
manufacturing overhead and selling and administrative costs.
The team felt it was important to carefully plan how it would go about implementing
the new ABC system at Classic Brass. Accordingly, it broke down the implementation
process into five steps:
Steps for Implementing Activity-Based Costing:
1.
2.
3.
4.
5.
Define activities, activity cost pools, and activity measures.
Assign overhead costs to activity cost pools.
Calculate activity rates.
Assign overhead costs to cost objects using the activity rates and activity measures.
Prepare management reports.
Step 1: Define Activities, Activity Cost Pools, and
Activity Measures
The first major step in implementing an ABC system is to identify the activities that will
form the foundation for the system. This can be difficult and time-consuming and involves
a great deal of judgment. A common procedure is for the individuals on the ABC implementation team to interview people who work in overhead departments and ask them to
describe their major activities. Ordinarily, this results in a very long list of activities.
The length of such lists of activities poses a problem. On the one hand, the greater the
number of activities tracked in the ABC system, the more accurate the costs are likely to
be. On the other hand, a complex system involving large numbers of activities is costly
to design, implement, maintain, and use. Consequently, the original lengthy list of activities is usually reduced to a handful by combining similar activities. For example, several actions may be involved in handling and moving raw materials—from receiving raw
materials on the loading dock to sorting them into the appropriate bins in the storeroom.
All of these activities might be combined into a single activity called material handling.
When combining activities in an ABC system, activities should be grouped together
at the appropriate level. Batch-level activities should not be combined with unit-level
Activity-Based Costing: A Tool to Aid Decision Making
295
activities or product-level activities with batch-level activities and so on. In general, it is
best to combine only those activities that are highly correlated with each other within a
level. For example, the number of customer orders received is likely to be highly correlated
with the number of completed customer orders shipped, so these two batch-level activities
(receiving and shipping orders) can usually be combined with little loss of accuracy.
At Classic Brass, the ABC team, in consultation with top managers, selected the following activity cost pools and activity measures:

Not applicable
The Customer Orders cost pool will be assigned all costs of resources that are consumed by taking and processing customer orders, including costs of processing paperwork and any costs involved in setting up machines for specific orders. The activity
measure for this cost pool is the number of customer orders received. This is a batch-level
activity because each order generates work that occurs regardless of whether the order is
for one unit or 1,000 units.
The Product Design cost pool will be assigned all costs of resources consumed by
designing products. The activity measure for this cost pool is the number of products
designed. This is a product-level activity because the amount of design work on a new product does not depend on the number of units ultimately ordered or batches ultimately run.
The Order Size cost pool will be assigned all costs of resources consumed as a consequence of the number of units produced, including the costs of miscellaneous factory
supplies, power to run machines, and some equipment depreciation. This is a unit-level
activity because each unit requires some of these resources. The activity measure for this
cost pool is machine-hours.
The Customer Relations cost pool will be assigned all costs associated with maintaining relations with customers, including the costs of sales calls and the costs of entertaining customers. The activity measure for this cost pool is the number of customers the
company has on its active customer list. The Customer Relations cost pool represents a
customer-level activity.
The Other cost pool will be assigned all overhead costs that are not associated with
customer orders, product design, the size of the orders, or customer relations. These costs
mainly consist of organization-sustaining costs and the costs of unused, idle capacity.
These costs will not be assigned to products because they represent resources that are not
consumed by products.
It is unlikely that any other company would use exactly the same activity cost pools
and activity measures that were selected by Classic Brass. Because of the amount of
judgment involved, the number and definitions of the activity cost pools and activity measures used by companies vary considerably.
The Mechanics of Activity-Based Costing
Step 2: Assign Overhead Costs to Activity Cost Pools
Exhibit 7–4 shows the annual overhead costs (both manufacturing and nonmanufacturing)
that Classic Brass intends to assign to its activity cost pools. Notice the data in the exhibit are
organized by department (e.g., Production, General Administrative, and Marketing). This is
because the data have been extracted from the company’s general ledger. General ledgers

usually classify costs within the departments where the costs are incurred. For example,
salaries, supplies, rent, and so forth incurred in the marketing department are charged to that
department. The functional orientation of the general ledger mirrors the presentation of costs
in the absorption income statement in Exhibit 7–2. In fact, you’ll notice the total costs for
the Production Department in Exhibit 7–4 ($1,000,000) equal the total manufacturing overhead costs from the income statement in Exhibit 7–2. Similarly, the total costs for the General Administrative and Marketing Departments in Exhibit 7–4 ($510,000 and $300,000)
equal the marketing and general and administrative expenses shown in Exhibit 7–2.
Three costs included in the income statement in Exhibit 7–2—direct materials,
direct labor, and shipping—are excluded from the costs shown in Exhibit 7–4. The
ABC team purposely excluded these costs from Exhibit 7–4 because the existing cost
system can accurately trace direct materials, direct labor, and shipping costs to products. There is no need to incorporate these direct costs in the activity-based allocations
of indirect costs.
Classic Brass’s activity-based costing system will divide the nine types of overhead
costs in Exhibit 7–4 among its activity cost pools via an allocation process called firststage allocation. The first-stage allocation in an ABC system is the process of assigning
functionally organized overhead costs derived from a company’s general ledger to the
activity cost pools.
First-stage allocations are usually based on the results of interviews with employees
who have first-hand knowledge of the activities. For example, Classic Brass needs to
allocate $500,000 of indirect factory wages to its five activity cost pools. These allocations will be more accurate if the employees who are classified as indirect factory
workers (e.g., supervisors, engineers, and quality inspectors) are asked to estimate what
percentage of their time is spent dealing with customer orders, with product design, with
processing units of product (i.e., order size), and with customer relations. These interviews are conducted with considerable care. Those who are interviewed must thoroughly
understand what the activities encompass and what is expected of them in the interview.
In addition, departmental managers are typically interviewed to determine how the nonpersonnel costs should be distributed across the activity cost pools. For example, the
Classic Brass production manager would be interviewed to determine how the $300,000
of factory equipment depreciation (shown in Exhibit 7–4) should be allocated to the
activity cost pools. The key question that the production manager would need to answer
is “What percentage of the available machine capacity is consumed by each activity such
as the number of customer orders or the number of units processed (i.e., size of orders)?”
The results of the interviews at Classic Brass are displayed in Exhibit 7–5. For example, factory equipment depreciation is distributed 20% to Customer Orders, 60% to Order
Size, and 20% to the Other cost pool. The resource in this instance is machine time.
According to the estimates made by the production manager, 60% of the total available

AN ABC APPLICATION IN THE CONSTRUCTION INDUSTRY
Researchers from the United States and the Republic of Korea studied how a Korean manufacturer
assigned the indirect costs of supplying reinforced steel bars (also called rebar) to various construction projects. The company’s traditional cost system assigned all indirect costs to projects using
rebar tonnage as the allocation base. Its ABC system had 10 activities that assigned indirect costs
to projects using activity measures such as number of orders, number of sheets, number of distributing runs, number of production runs, and number of inspections.
The traditional and ABC systems assigned the following overhead costs to three construction
projects called Commercial, High-Rise Condo, and Heavy Civil:

machine time was used to actually process units to fill orders. This percentage is entered
in the Order Size column. Each customer order requires setting up, which also requires
machine time. This activity consumes 20% of the total available machine time and is
entered under the Customer Orders column. The remaining 20% of available machine
time represents idle time and is entered under the Other column.
Exhibit 7–5 and many of the other exhibits in this chapter are presented in the form of
Excel spreadsheets. All of the calculations required in activity-based costing can be done
by hand. Nevertheless, setting up an activity-based costing system on a spreadsheet or
using special ABC software can save a lot of work—particularly in situations involving
many activity cost pools and in organizations that periodically update their ABC systems.
We will not go into the details of how all of the percentages in Exhibit 7–5 were
determined. However, note that 100% of the factory building lease has been assigned
to the Other cost pool. Classic Brass has a single production facility. It has no plans to
expand or to sublease any excess space. The cost of this production facility is treated as
an organization-sustaining cost because there is no way to avoid even a portion of this
cost if a particular product or customer were to be dropped. (Remember that organizationsustaining costs are assigned to the Other cost pool and are not allocated to products.) In
contrast, some companies have separate facilities for manufacturing specific products.
The costs of these separate facilities could be directly traced to the specific products.
Once the percentage distributions in Exhibit 7–5 have been established, it is easy to
allocate costs to the activity cost pools. The results of this first-stage allocation are displayed in Exhibit 7–6. Each cost is allocated across the activity cost pools by multiplying
it by the percentages in Exhibit 7–5. For example, the indirect factory wages of $500,000
are multiplied by the 25% entry under Customer Orders in Exhibit 7–5 to arrive at the
$125,000 entry under Customer Orders in Exhibit 7–6. Similarly, the indirect factory
wages of $500,000 are multiplied by the 40% entry under Product Design in Exhibit 7–5
to arrive at the $200,000 entry under Product Design in Exhibit 7–6. All of the entries in
Exhibit 7–6 are computed in this way.
Activity-Based Costing: A Tool to Aid Decision Making
299
Now that the first-stage allocations to the activity cost pools have been completed,
the next step is to compute the activity rates.
Step 3: Calculate Activity Rates
The activity rates that will be used for assigning overhead costs to products and customers
are computed in Exhibit 7–7. The ABC team determined the total activity for each cost pool
that would be required to produce the company’s present product mix and to serve its present
customers. These numbers are listed in Exhibit 7–7. For example, the ABC team found that
400 new product designs are required each year to serve the company’s present customers.
The activity rates are computed by dividing the total cost for each activity by its total activity. For example, the $320,000 total annual cost for the Customer Orders cost pool (which
was computed in Exhibit 7–6) is divided by the total of 1,000 customer orders per year to
arrive at the activity rate of $320 per customer order. Similarly, the $252,000 total cost for the
Product Design cost pool is divided by the total number of designs (i.e., 400 product designs)
to determine the activity rate of $630 per design. Note that an activity rate is not computed
for the Other category of costs. This is because the Other cost pool consists of organizationsustaining costs and costs of idle capacity that are not allocated to products and customers.
The rates in Exhibit 7–7 indicate that on average a customer order consumes resources
that cost $320; a product design consumes resources that cost $630; a unit of product consumes resources that cost $19 per machine-hour; and maintaining relations with a customer consumes resources that cost $1,470. Note that these are average figures. Some
members of the ABC design team at Classic Brass argued that it would be unfair to charge
all new products the same $630 product design cost regardless of how much design time
they actually require. After discussing the pros and cons, the team concluded that it would
not be worth the effort at the present time to keep track of actual design time spent on each
new product. They felt that the benefits of increased accuracy would not be great enough
to justify the higher cost of implementing and maintaining the more detailed costing system. Similarly, some team members were uncomfortable assigning the same $1,470 cost
to each customer. Some customers are undemanding—ordering standard products well in
advance of their needs. Others are very demanding and consume large amounts of marketing and administrative staff time. These are generally customers who order customized
products, who tend to order at the last minute, and who change their minds. While everyone agreed with this observation, the data that would be required to measure individual
customers’ demands on resources were not currently available. Rather than delay implementation of the ABC system, the team decided to defer such refinements to a later date.
Before proceeding further, it would be helpful to get a better idea of the overall process
of assigning costs to products and other cost objects in an ABC system. Exhibit 7–8 provides

go over this exhibit. In particular, note that the Other category, which contains organizationsustaining costs and costs of idle capacity, is not allocated to products or customers.
Step 4: Assign Overhead Costs to Cost Objects
LO7–4
Assign costs to a cost
object using a second-stage
allocation.
The fourth step in the implementation of activity-based costing is called second-stage
allocation. In the second-stage allocation, activity rates are used to apply overhead costs
to products and customers. First, we will illustrate how to assign costs to products followed by an example of how to assign costs to customers.
The data needed by the ABC team to assign overhead costs to Classic Brass’s two
products—standard stanchions and custom compass housings—are as follows:
Standard Stanchions
1.
2.
3.
This product line does not require any new design resources.
30,000 units were ordered during the year, comprising 600 separate orders.
Each stanchion requires 35 minutes of machine time for a total of 17,500
machine-hours.
Custom Compass Housings
1.
2.
3.
4.
This is a custom product that requires new design resources.
There were 400 orders for custom compass housings. Orders for this product
are placed separately from orders for standard stanchions.
There were 400 custom designs prepared. One custom design was prepared
for each order.
Because some orders were for more than one unit, a total of 1,250 custom
compass housings were produced during the year. A custom compass housing
requires an average of 2 machine-hours for a total of 2,500 machine-hours.
Notice, 600 customer orders were placed for standard stanchions and 400 customer
orders were placed for custom compass housings, for a total of 1,000 customer orders.
All 400 product designs related to custom compass housings; none related to standard
stanchions. Producing 30,000 standard stanchions required 17,500 machine-hours and

HOW MUCH DOES IT COST TO HANDLE A PIECE OF LUGGAGE?
It costs an airline about $15 to carry a piece of checked luggage from one destination another. The
activity “transporting luggage” consists of numerous sub-activities such as tagging bags, sorting
them, placing them on carts, transporting bags planeside, loading them into the airplane, and delivering them to carousels and connecting flights.
A variety of employees invest a portion of their labor hours “transporting luggage” including
ground personnel, check-in agents, service clerks, baggage service managers, and maintenance
workers. In total, labor costs comprise $9 per bag. Airlines also spend millions of dollars on baggage equipment, sorting systems, carts, tractors, and conveyors, as well as rental costs related to
bag rooms, carousels, and offices. They also pay to deliver misplaced bags to customers’ homes
and to compensate customers for lost bags that are never found. These expenses add up to about
$4 per bag. The final expense related to transporting luggage is fuel costs, which average about
$2 per bag.
Many major airlines now charge fees for checked bags. United Airlines expects to collect $275
million annually for its first and second bag fees.

producing 1,250 custom compass housings required 2,500 machine-hours, for a total of
20,000 machine-hours.
Exhibit 7–9 illustrates how overhead costs are assigned to the standard stanchions
and custom compass housings. For example, the exhibit shows that $192,000 of overhead costs are assigned from the Customer Orders activity cost pool to the standard
stanchions ($320 per order 3 600 orders). Similarly, $128,000 of overhead costs are
assigned from the Customer Orders activity cost pool to the custom compass housings

($320 per order 3 400 orders). The Customer Orders cost pool contained a total of
$320,000 (see Exhibit 7–6 or 7–7) and this total amount has been assigned to the two
products ($192,000 1 $128,000 5 $320,000).
Exhibit 7–9 shows that a total of $952,000 of overhead costs is assigned to Classic Brass’s two product lines—$524,500 to standard stanchions and $427,500 to custom compass housings. This amount is less than the $1,810,000 of overhead costs
included in the ABC system. Why? The total amount of overhead assigned to products does not match the total amount of overhead cost in the ABC system because
the ABC team purposely did not assign the $367,500 of Customer Relations and
$490,500 of Other costs to products. The Customer Relations activity is a customerlevel activity and the Other activity is an organization-sustaining activity—neither
activity is caused by products. As shown below, when the Customer Relations and
Other activity costs are added to the $952,000 of overhead costs assigned to products,
the total is $1,810,000.

Next, we describe another example of second-stage allocation—assigning activity
costs to customers. The data needed by Classic Brass to assign overhead costs to one of
its customers—Windward Yachts—are as follows:
Windward Yachts
1.
The company placed a total of three orders.
a. Two orders were for 150 standard stanchions per order.
b. One order was for a single custom compass housing unit.
2. A total of 177 machine-hours were used to fulfill the three customer orders.
a. The 300 standard stanchions required 175 machine-hours.
b. The custom compass housing required 2 machine-hours.
3. Windward Yachts is one of 250 customers served by Classic Brass.
Exhibit 7–10 illustrates how the ABC system assigns overhead costs to this customer. As shown in Exhibit 7–10, the ABC team calculated that $6,423 of overhead
costs should be assigned to Windward Yachts. The exhibit shows that Windward Yachts
is assigned $960 ($320 per order 3 3 orders) of overhead costs from the Customer
Orders activity cost pool; $630 ($630 per design 3 1 design) from the Product Design
cost pool; $3,363 ($19 per machine-hour 3 177 machine-hours) from the Order Size
cost pool; and $1,470 ($1,470 per customer 3 1 customer) from the Customer Relations cost pool.

Assigning Overhead Costs to Customers
With second-stage allocations complete, the ABC design team was ready to turn its attention to creating reports that would help explain the company’s first ever net operating loss.
Step 5: Prepare Management Reports
The most common management reports prepared with ABC data are product and customer profitability reports. These reports help companies channel their resources to their
most profitable growth opportunities while at the same time highlighting products and
customers that drain profits. We begin by illustrating a product profitability report followed by a customer profitability report.
The Classic Brass ABC team realized that the profit from a product, also called the
product margin, is a function of the product’s sales and the direct and indirect costs that
the product causes. The ABC cost allocations shown in Exhibit 7–9 only summarize each
product’s indirect (i.e., overhead) costs. Therefore, to compute a product’s profit (i.e.,
product margin), the design team needed to gather each product’s sales and direct costs
in addition to the overhead costs previously computed. The pertinent sales and direct cost
data for each product are shown below. Notice the numbers in the total column agree with
the income statement in Exhibit 7–2.

Having gathered the above data, the design team created the product profitability
report shown in Exhibit 7–11. The report revealed that standard stanchions are profitable,
with a positive product margin of $906,250, whereas the custom compass housings are
unprofitable, with a negative product margin of $49,500. Keep in mind that the product
profitability report purposely does not include the costs in the Customer Relations and
Other activity cost pools. These costs, which total $858,000, were excluded from the

by customers, not products. The Other costs are organization-sustaining costs and unused

The results show that 18.3% of respondents use ABC to allocate production costs to cost
objects and 42% use standard costing for the same purpose. ABC is used by at least 13% of
respondents within all functional departments across the value chain. Many companies do not allocate nonproduction costs to cost objects.

Using these data and the data from Exhibit 7–10, the design team created the customer profitability report shown in Exhibit 7–12. The report revealed that the customer
margin for Windward Yachts is $699. A similar report could be prepared for each of

Classic Brass’s 250 customers, thereby enabling the company to cultivate relationships
with its most profitable customers, while taking steps to reduce the negative impact of
unprofitable customers.
Comparison of Traditional and ABC Product Costs
The ABC team used a two-step process to compare its traditional and ABC product costs.
First, the team reviewed the product margins reported by the traditional cost system.
Then, it contrasted the differences between the traditional and ABC product margins.
Product Margins Computed Using the Traditional Cost System
Classic Brass’s traditional cost system assigns only manufacturing costs to products—
this includes direct materials, direct labor, and manufacturing overhead. Selling and
administrative costs are not assigned to products. Exhibit 7–13 shows the product margins reported by Classic Brass’s traditional cost system. We will explain how these margins were calculated in three steps. First, the sales and direct materials and direct labor
cost data are the same numbers used by the ABC team to prepare Exhibit 7–11. In other
words, the traditional cost system and the ABC system treat these three pieces of revenue
and cost data identically.
Second, the traditional cost system uses a plantwide overhead rate to assign manufacturing overhead costs to products. The numerator for the plantwide overhead rate is
$1,000,000, which is the total amount of manufacturing overhead shown on the income
statement in Exhibit 7–2. The footnote in Exhibit 7–2 mentions that the traditional cost
system uses machine-hours to assign manufacturing overhead costs to products. The
Order Size activity in Exhibit 7–7 used 20,000 machine-hours as its level of activity.
These same 20,000 machine-hours would be used in the denominator of the plantwide
overhead rate, which is computed as follows:
Plantwide overhead rate 5
5
Total estimated manufacturing overhead
Total estimated machine-hours
$1,000,000
20,000 machine-hours
5 $50 per machine-hour
Because 17,500 machine-hours were worked on standard stanchions, this product line
is assigned $875,000 (17,500 machine-hours 3 $50 per machine-hour) of manufacturing
overhead cost. Similarly, the custom compass housings required 2,500 machine-hours, so
this product line is assigned $125,000 (2,500 machine-hours 3 $50 per machine-hour)
of manufacturing overhead cost. The sales of each product minus its cost of goods sold
equals the product margin of $615,750 for standard stanchions and $258,000 for custom
compass housings.
Notice, the net operating loss of $1,250 shown in Exhibit 7–13 agrees with the loss
reported in the income statement in Exhibit 7–2 and with the loss shown in the table
beneath Exhibit 7–11. The company’s total sales, total costs, and its resulting net operating loss are the same regardless of whether you are looking at the absorption income
statement in Exhibit 7–2, the ABC product profitability analysis depicted on page 304,
or the traditional product profitability analysis in Exhibit 7–13. Although the “total pie”
remains constant across the traditional and ABC systems, what differs is how the pie is
divided between the two product lines. The traditional product margin calculations suggest that standard stanchions are generating a product margin of $615,750 and the custom
compass housings a product margin of $258,000. However, these product margins differ
Activity-Based Costing: A Tool to Aid Decision Making
EXHIBIT 7–13
Product Margins—Traditional Costing System
from the ABC product margins reported in Exhibit 7–11. Indeed, the traditional cost system is sending misleading signals to Classic Brass’s managers about each product’s profitability. Let’s explain why.
The Differences between ABC and Traditional Product Costs
The changes in product margins caused by switching from the traditional cost system to
the activity-based costing system are shown below:

$(307,500)
The traditional cost system overcosts the standard stanchions and consequently reports
an artificially low product margin for this product. The switch to an activity-based view of
product profitability increases the product margin on standard stanchions by $290,500. In
contrast, the traditional cost system undercosts the custom compass housings and reports
an artificially high product margin for this product. The switch to activity-based costing
decreases the product margin on custom compass housings by $307,500.
The reasons for the change in reported product margins between the two costing
methods are revealed in Exhibit 7–14. The top portion of the exhibit shows each product’s direct and indirect cost assignments as reported by the traditional cost system in
Exhibit 7–13. For example, Exhibit 7–14 includes the following costs for standard stanchions: direct materials, $905,500; direct labor, $263,750; and manufacturing overhead,
$875,000. Each of these costs corresponds with those reported in Exhibit 7–13. Notice,
the selling and administrative costs of $875,000 are purposely not allocated to products
because these costs are considered to be period costs when using traditional costing.
Similarly, the bottom portion of Exhibit 7–14 summarizes the direct and indirect cost
assignments as reported by the activity-based costing system in Exhibit 7–11. The only
new information in Exhibit 7–14 is shown in the two columns of percentages. The first
column of percentages shows the percentage of each cost assigned to standard stanchions.
For example, the $905,500 of direct materials cost traced to standard stanchions is 92.9%
of the company’s total direct materials cost of $975,000. The second column of percentages does the same thing for custom compass housings.
